Vultr SLA：提供 100% 节点在线时间和网络在线时间保障

今天在浏览 Vultr 的网站，发现 Vultr 是明确写了会提供 SLA 保障的，并且如果达不到 SLA 标准，会进行赔偿。而且是对于 VPS 的在线时间和网络的在线时间都是 100% 的 SLA 保障，对于丢包率，也保障做到 0%（不知道对于中国大陆是不是也敢这么保障？）一旦发现 SLA 不达标，会进行相应的赔偿，赔偿是根据宕机时间进行的，赔偿相应的 VPS 的使用时长。

一、Vultr SLA 原文

来源：https://www.vultr.com/legal/sla/

100% Uptime Guarantee

Vultr offers a 100% uptime guarantee via this Service Level Agreement based on network and host node availability. Collectively, these guarantees may be referred to as the “SLA.” This SLA is provided as a supplement to the Hosting Terms and Conditions You agreed to in becoming a Vultr customer, which is hereby incorporated by reference as an indispensable part of this SLA.

This uptime guarantee is applicable on a per-service-item basis and is not applied to Your entire invoice. For example, if You have fifty (50) servers with Us, and one (1) of those servers experiences downtime, any credit due to You under this uptime guarantee would be proportional to that one (1) server’s downtime and not Your entire account with Us. This uptime guarantee does not apply to the accessibility of Vultr’s web property, DNS servers, API, or control panel.

Packet Loss and Latency

Vultr does not proactively monitor the packet loss or transmission latency of specific customers. Vultr does, however, proactively monitor the aggregate packet loss and transmission latency within its LAN and WAN. In the event that Vultr discovers (either from its own efforts or after being notified by You) that You are experiencing packet loss in excess of one percent (1%) (“Excess Packet Loss”) between your instance and one hop from Vultr’s border router(s) (first hop of egress providers router) and You notify Vultr via a support ticket (or Vultr has notified You of an event), Vultr will take all actions necessary to determine the source of the Excess Packet Loss/Latency.

Limitations

The uptime guarantee ONLY applies to network and instance availability during normal operation. The uptime guarantee does NOT apply to server-side software uptime. Any outage due to server software, operating systems, improper configurations, denial of service attack against your instance, instance suspension, instance paused/halted for any reason, or any other non-network or non-“host node” outage, for any reason and whether or not such outage is caused by Us due to upgrading, troubleshooting or performing any other tasks, is not subject to this uptime guarantee. The guarantee does NOT apply when a scheduled maintenance occurs with a minimum of twenty-four (24) hour notice or in the event a time critical patch/update must be applied as long as the outage/packetloss does not exceed ten (10) minutes.

Furthermore, none of the guarantees in this SLA may be combined. For example, a hardware outage that also disrupts network activity will not qualify You for two (2) separate credits. If for example, a hardware outage was the basis for the connectivity loss, the entire event will count as one single outage for the purpose of determining applicable credit.

Outage Credits

In accordance with the procedure outlined below, you must initiate a support ticket and request that a credit be applied to your account. Merely initiating a support ticket related to an outage will not result in any credit to your account. Initiating a support ticket and requesting a credit is what triggers an event for any potential credits; however, Vultr must still determine, in its sole discretion, whether or not an eligible outage has occurred. If Vultr determines that an eligible outage has occurred, then the ticket you generated will be used to generate a credit using the table below:

How To Obtain Your Credit

In order to receive any credit offered under this SLA, You must initiate a support ticket related to the event AND expressly request that We issue a credit. DO NOT ASSUME THAT WE ARE AWARE OF YOUR OUTAGE. Your outage may be wholly unrelated to Vultr’s services, so unless You contact Us via a support ticket, We may not be aware any problem exists. Outages related to hardware or other services or events not under Vultr’s control are not eligible for any guarantee or credit offered under this SLA.

You may initiate such support ticket via e-mail to support [at] vultr [dot] com, or the my.vultr.com interface. Whichever method You choose, You MUST obtain a Vultr ticket number as proof that you initiated a support ticket related to the outage, and the support ticket MUST ask for a credit related to the outage. As stated herein, the timestamp on the support ticket will mark the beginning of an outage should Vultr determine that an eligible outage occurred. If Vultr was aware of the issue before You were, Vultr may notify You of the outage. In such instance, You must still initiate a support ticket to confirm that You are aware of the outage, and such support ticket must still also request a credit. To be clear, You must have a support ticket number in order to receive any credits under this SLA.

You agree and acknowledge that all other terms, limitations, exclusions, disclaimers and requirements contained in Vultr’s Hosting Terms and Conditions apply to this SLA.
