2.那我的VPS带宽怎么选择？
很多朋友对这个行业一知半解，我们在选择VPS套餐的时候，一定要记住一点在自己的预算范围内，选择性价比最高的服务器和VPS产品，产品是可选择的，我们的选择过程是灵活的，无论是不限流量的1Mbps、5Mbps、10Mbps，或者是限制流量的100Mbps甚至1Gbps，都不重要，重要的是符合自己业务，访问速度快、稳定性好、价格可接受。
不限流量的小带宽VPS和限制流量的大带宽VPS各有优缺点，我们一定要记住，存在即合理。
小带宽不限流量VPS优点：
1. 成本效益：对于流量需求较大但对实时速度要求不高的网站或应用，这种配置可以节省费用，因为用户无需担心超出流量限制而产生的额外费用。
2. 稳定流量消耗：适合静态内容为主的网站或者日间流量波动较小的服务，只要流量在带宽承受范围内持续传输，不会因为突发的流量高峰导致服务中断。
3. 长期在线服务：对于需要全天候运行、数据同步等任务，即使带宽较小，只要不是对时间敏感型的应用，也可以保证不间断的数据交换。
小带宽不限流量VPS缺点：
1. 访问速度受限：由于带宽较小，当有大量并发访问时，网页加载速度和文件下载速度会受到显著影响，用户体验可能不佳。
2. 无法应对突发流量：如果站点突然火爆或遭受DDoS攻击，小带宽将迅速饱和，导致服务不可用。
3. 不适合媒体流、视频会议等高带宽应用：对于涉及高清视频播放、音频流、实时交互等应用来说，小带宽显然无法满足其正常运行的需求。
大带宽限制流量VPS优点：
1. 高速响应能力：大带宽意味着更高的网络吞吐量，能够提供更快的内容加载速度，这对于提高用户体验至关重要。
2. 处理突发流量：在面对瞬时高流量需求时，大带宽服务器能更好地承载并分配流量，降低因带宽不足导致的服务崩溃风险。
3. 支持高负载应用：适用于运行大型数据库查询、实时通信服务、高清视频流媒体、大型多人在线游戏等对带宽要求较高的业务场景。
大带宽限制流量VPS缺点：
1. 超流量计费：当流量被严格限制时，超流量部分可能会产生额外计费。
2. 流量管理复杂：需要密切关注和有效管理每月流量配额，防止业务量上去导致流量超标额外支出或服务暂停。
3. 稳定性依赖于流量控制：如果未能合理规划流量使用，一旦达到流量上限，即使硬件资源充足，也会因为带宽限制而使得服务降级或停止。
3.如何选择商家及判断商家实力？
我们都知道，三大运营商被称为以一级运营商
一级运营商
一级运营商在互联网带宽量属于国内带宽量最大的存在，国外也是一样，一级运营商带宽属于最大存在，机房运维管理一般承包给第三方去管理。
主营主营：机柜租赁、大带宽销售、IP地址广播、公有云（天翼云、联通云等）、超大型企业招投标项目等
二级运营商
二级运营商为IDC服务商，也就是承包机房模块、自建机房、承包机柜和带宽，上层架构交换机对交换机下方的网络和设备进行管理，机房运维一般会现场驻扎人员随时去维护
主营业务：机柜租赁、大带宽销售、IP地址出租、私有云、混合云、CDN、机房代运维、服务器托管、服务器租用、云服务器、算力租赁、VPS、招投标项目等
三级运营商
三级运营商居多为租赁一级或者二级运营商的机柜和服务器进行销售，机房运维需要依靠二级运营商协助管理
主营业务：服务器托管、服务器租用、VPS、虚拟空间销售等
上面三种只是大部分情况，对于用户而言更多的是无法判断二级和三级运营商，我们要知道，无论是二级还是三级运营商，对我们提供稳定的性价比产品和快速的售后服务才是关键。避免在VPS和主机租用时，因只单方面考虑价格而选择了商家自身冗余资源较少、网络稳定性差、售后体验不及时等问题导致得不偿失。
4.月付好还是年付好？
在选择虚拟主机或云服务器时，月付通常是一种更为灵活和安全的支付方式。对于个人用户或者初创项目来说，业务需求可能会随着时间和项目的进展而变化，月付能够最大程度地减少财务风险，避免因提前预付一年费用后，由于各种原因（如项目暂停、需求变更或服务质量不达标等）导致的资金浪费。年付虽然通常会带来一定的折扣优惠，但服务商信誉不高或是市场上的小商家，年付可能会增加潜在的风险，尤其是商家可能存在经营不善甚至跑路的情况。因此，在考虑是否进行长期预付费之前，充分考察服务商的行业口碑、经营历史、客户评价和服务保障体系是非常重要的。
如果有条件，使用PayPal等第三方支付工具付款是个不错的选择，不仅是因为其便捷性，更重要的是它为消费者提供了购物保护机制。在一定期限内（通常是180天），买家如果遭遇了商家跑路可以向PayPal发起申诉，待争议完成后钱会退还给你。这对于保障消费者权益有着积极作用。然而，在享受这一保障的同时，也应注意合理合规地使用这些服务，避免无端争议可能给商家带来的负面影响。
5.如果我使用了一周想退款怎么办？
购买服务之前请详细阅读商家条例，如遇到使用一周想退款此类情况，首先是和商家充分协商，但是，一般超出1天或者3天等试用期，商家有权不进行退款的，如为违规业务，商家是不会退款，可能会记录你的违规业务记录。
6.为什么我网站内部出现问题售后不处理？
服务器厂商只负责因服务器网络和服务器设备等问题，自行导致故障的售后技术，因客户操作严重不当导致的服务器故障和用户网站或者业务内部的问题不在服务器厂商售后范围，即使处理也属于增值服务需要额外收费的。
7.PayPal为什么会自动扣钱？
因为你使用了PayPal订阅来付款，大部分商家都是订阅方式付款，支付时请看清楚是否使用了订阅支付，否则次月PayPal将如期支付相同金额给卖家，已经订阅的账单可在PayPal后台取消自动支付。
8.我直接在PayPal申请退款可以吗？
不可以。交易一旦完成，申请退款请与商家协商。任何在PayPal申请的退款属于争议范畴，即商家将收到处罚。如果你还在使用商家服务申请争议后你将面临被删除服务和账号的风险。
1. Tips for purchasing overseas servers and VPS lines
When entering the merchant's official website to purchase a server, if the line is not specified, the default speed of overseas servers and VPS is very slow, and the lines used by different operators of China Telecom/China Unicom/China Mobile to access the server are also different. Currently, the ones that have attracted much attention in the network line market include China Telecom’s CN2 GIA (CN2 only), China Unicom’s AS9929 (as9929 only), and China Unicom’s AS4837 (also known as CERAN’s cuvip, as4837 only). The concept of "three networks" here refers to whether the user uses the network access server of China Telecom, China Unicom or China Mobile, data transmission will be mandatory through these specific lines. Therefore, naming such lines as CN2 only, AS9929 only and AS4837 only can more accurately reflect their characteristics. So far, the QOS level of China Telecom’s international lines is roughly: CN2 GIA (AS4809) > CN2 GT (AS4809) > Telecom 163 Network (AS4134). The QOS level of China Unicom’s international lines is roughly: China Unicom A Network (AS9929) > China Unicom 169 Network (AS4837), the QOS level of China Mobile’s international lines is roughly: CMIN2 (AS58807) > CMI (AS9808), among which the CMIN2 line is China Mobile’s newly released China Mobile Premium Network, which is directly connected to China Telecom CN2 GIA and China Unicom A Internet competition. At present, because China Unicom has few international export users and large bandwidth redundancy, AS4837 is very good, and many merchants have launched AS4837 lines.In addition, in addition to the lines of China's three major operators, there are also some high-quality network lines in Asia that are friendly to mainland China, such as Japan's SoftBank (SoftBank), Japan's KDDI, Japan's IIJ (Internet Initiative Japan), South Korea's LG, South Korea's SK, Taiwan's HiNet (Chunghwa Telecom) and Hong Kong's HGC (Hutchison Global Communications), etc. It is recommended to test this first, and it is most important to suit your own business.
In summary, for domestic users to choose to access overseas hosts, it is recommended to give priority to products with triple network or triple network backhaul support and use high-quality lines such as CN2 GIA, AS9929, CMIN2, AS4837 or CMI. For overseas users to access overseas hosts, just choose a line that is friendly to the place of visit.
2. How to choose my VPS bandwidth?
Many friends have little knowledge of this industry. When we choose a VPS package, we must remember to choose the most cost-effective server and VPS product within our own budget. The products are optional and our selection process is flexible. Whether it is 1Mbps, 5Mbps, 10Mbps with unlimited traffic, or 100Mbps or even 1Gbps with limited traffic, it doesn’t matter. What matters is that it suits your business, has fast access speed, good stability, and acceptable price.
A small-bandwidth VPS with unlimited traffic and a large-bandwidth VPS with limited traffic each have their own advantages and disadvantages. We must remember that existence is reasonable.
Advantages of small bandwidth unlimited traffic VPS:
1. Cost-effectiveness: For websites or applications with large traffic demands but low real-time speed requirements, this configuration can save costs because users do not need to worry about additional charges for exceeding traffic limits.
2. Stable traffic consumption: It is suitable for websites with mainly static content or services with small traffic fluctuations during the day. As long as the traffic continues to be transmitted within the bandwidth capacity, the service will not be interrupted due to sudden traffic peaks.
3. Long-term online service: For tasks that require round-the-clock operation, data synchronization, etc., even if the bandwidth is small, as long as the application is not time-sensitive, uninterrupted data exchange can be guaranteed.
Disadvantages of small bandwidth unlimited traffic VPS:
1. Limited access speed: Due to the small bandwidth, when there are a large number of concurrent accesses, the web page loading speed and file download speed will be significantly affected, and the user experience may be poor.
2. Unable to cope with burst traffic: If the site suddenly becomes popular or suffers a DDoS attack, the small bandwidth will be quickly saturated, resulting in service unavailability.
3. Not suitable for high-bandwidth applications such as media streaming and video conferencing: For applications involving high-definition video playback, audio streaming, real-time interaction, etc., small bandwidth is obviously unable to meet their normal operation needs.
Advantages of VPS with large bandwidth limit traffic:
1. High-speed response capability: Large bandwidth means higher network throughput and can provide faster content loading speed, which is crucial to improving user experience.
2. Handle burst traffic: When faced with instantaneous high traffic demands, large-bandwidth servers can better carry and distribute traffic, reducing the risk of service collapse caused by insufficient bandwidth.
3. Support high-load applications: suitable for running large database queries, real-time communication services, high-definition video streaming, massive multiplayer online games and other business scenarios with high bandwidth requirements.
Disadvantages of VPS with large bandwidth limit traffic:
1. Excess traffic billing: When traffic is strictly restricted, additional charges may be incurred for the excess traffic part.
2. Complex traffic management: Monthly traffic quotas need to be closely monitored and effectively managed to prevent increased business volume from causing additional expenditures or service suspension due to excessive traffic.
3. Stability depends on traffic control: If traffic usage is not properly planned, once the traffic limit is reached, even if the hardware resources are sufficient, the service will be degraded or stopped due to bandwidth limitations.
3. How to choose merchants and judge their strength?
We all know that the three major operators are called first-tier operators
Tier 1 operator
Tier 1 operators have the largest amount of Internet bandwidth in China, and the same applies abroad. Tier 1 operators have the largest bandwidth, and computer room operation and maintenance management is generally contracted to a third party for management.
Main business: cabinet rental, large bandwidth sales, IP address broadcast, public cloud (Tianyi Cloud, China Unicom Cloud, etc.), very large enterprise bidding projects, etc.
Secondary operator
The secondary operator is an IDC service provider, that is, contracted computer room modules, self-built computer rooms, contracted cabinets and bandwidth. The upper-layer architecture switches manage the network and equipment below the switches. The computer room operation and maintenance generally requires on-site personnel to perform maintenance at any time.
Main business: cabinet rental, large bandwidth sales, IP address rental, private cloud, hybrid cloud, CDN, computer room operation and maintenance, server hosting, server rental, cloud server, computing power rental, VPS, bidding projects, etc.
Level 3 carrier
Most of the third-level operators rent the cabinets and servers of the first-level or second-level operators for sale. The operation and maintenance of the computer room needs to rely on the assistance and management of the second-level operators.
Main business: server hosting, server rental, VPS, virtual space sales, etc.
The above three are just most cases. For users, it is more difficult to judge the second- and third-level operators. We must know that whether they are second-level or third-level operators, they can provide us with stable cost-effective products and fast delivery. After-sales service is the key. When renting a VPS or a host, avoid choosing a business that only considers price unilaterally due to problems such as less redundant resources, poor network stability, and untimely after-sales experience, resulting in more losses than gains.
4. Is it better to pay monthly or annually?
When choosing a web host or cloud server, monthly payment is usually a more flexible and secure payment method. For individual users or start-up projects, business needs may change over time and as the project progresses. Monthly payment can minimize financial risks and avoid having to pay for one year in advance due to various reasons (such as project suspension). , demand changes or service quality substandard, etc.) resulting in waste of funds. Although annual payment usually brings certain discounts, if the service provider does not have a high reputation or is a small merchant in the market, annual payment may increase potential risks, especially if the merchant may suffer from poor management or even run away. Therefore, before considering whether to make long-term prepayment, it is very important to fully examine the service provider's industry reputation, business history, customer reviews and service guarantee system.
If possible, using third-party payment tools such as PayPal to pay is a good choice, not only because of its convenience, but more importantly, it provides consumers with a shopping protection mechanism. Within a certain period of time (usually 180 days), if the buyer encounters a merchant running away, he can file a complaint with PayPal, and the money will be returned to you after the dispute is completed. This has a positive effect on protecting consumer rights. However, while enjoying this guarantee, you should also pay attention to using these services reasonably and compliantly to avoid the negative impact that unwarranted disputes may have on merchants.
5. What should I do if I use it for a week and want a refund?
Please read the merchant's regulations in detail before purchasing the service. If you encounter a situation where you want a refund after using it for a week, you must first fully negotiate with the merchant. However, generally if the trial period exceeds 1 day or 3 days, the merchant has the right not to refund. If it is illegal business, the merchant will not refund and may record your illegal business records.
6. Why is there no after-sales service to resolve internal problems on my website?
The server manufacturer is only responsible for after-sales technology for self-caused failures due to problems such as server network and server equipment. Server failures caused by serious improper customer operations and problems within the user's website or business are not within the scope of the server manufacturer's after-sales service. Even if they are dealt with, they are value-added services. Additional charges apply.
7. Why does PayPal automatically deduct money?
Because you used PayPal subscription to pay, most merchants pay by subscription. When paying, please check clearly whether you used subscription payment, otherwise PayPal will pay the same amount to the seller as scheduled in the next month. Bills that have been subscribed can be canceled in the PayPal backend. Automatic payments.
8. Can I apply for a refund directly through PayPal?
Can't. Once the transaction is completed, please negotiate with the merchant to apply for a refund. Any chargeback requested through PayPal is considered a dispute and the merchant will be subject to penalties. If you are still using merchant services to file a dispute, you will face the risk of having your service and account deleted.
