Hello there

We’re aware of an intermittent internal network congestion occurring at our Layer 2 switches, and this email is to let you know that we have outlined a maintenance windows to address it.

The maintenance is scheduled to take place starting Nov 29th, 2020. We expect this maintenance to result in a much more stable network environment for your Cloud Instance.

We will email you with updates with regard to the maintenance on https://status.cloudcone.com, if you haven’t already subscribed, please do.

I have outlined a few general questions about this maintenance and the underlying issue.

What will happen to my server during the maintenance?
Your server will be re-booted for the number of IPv4 addressed you have (if your server has two IPv4s, it will be re-booted twice, and likewise.)
A short network interruption should happen until your server is re-booted.
Cloud Firewall rules will need to be re-added, if you’re currently using it.
Is my server affected with the ongoing congestion?
Not all of our clients are affected, however, certain clients on certain Hypervisor Nodes are affected.

How is my server affected with the ongoing congestion?
Certain clients tend to experience an intermittent packet loss on their Compute Instance.
Certain clients tend to experience slower network speed within their Compute Instance.
Is my data affected?
No, nothing inside your Compute Instance is touched, as this is a network level maintenance.

Anything else I need to know?
The Cloud Firewall will be temporarily disabled until maintenance complete.
Adding IPv6 addresses will be temporarily disabled until maintenance complete.
Is this maintenance eligible for SLA credits?
Yes, SLA credits shall be give to customers who request.

Please bear with us until the maintenance is complete from our end. We also like you to know, that this is in our top priority!

你好

我们知道在我们的第2层交换机上发生间歇性内部网络拥塞，并且此电子邮件是为了通知您我们已经概述了维护窗口以解决此问题。

维护计划于2020年11月29日开始。我们希望此维护将为您的Cloud Instance提供更加稳定的网络环境。

我们将通过https://status.cloudcone.com通过电子邮件向您发送有关维护的更新，如果您尚未订阅，请这样做。

我已经概述了有关此维护和潜在问题的一些一般性问题。

维护期间我的服务器会怎样？
将针对您拥有的IPv4数量重新启动服务器（如果您的服务器具有两个IPv4，则将重新启动两次，同样如此）。
在重新启动服务器之前，应该会发生短暂的网络中断。
如果您当前正在使用，则需要重新添加Cloud Firewall规则。
我的服务器是否受到持续的拥塞影响？
并非我们的所有客户端都受到影响，但是某些Hypervisor节点上的某些客户端也受到影响。

服务器受到持续的拥堵如何影响？
某些客户端在其计算实例上往往会遇到间歇性的数据包丢失。
某些客户端在其计算实例中往往会遇到较慢的网络速度。
我的数据受到影响吗？
不，您的计算实例内部没有任何问题，因为这是网络级别的维护。

我还有其他需要知道的吗？
在维护完成之前，云防火墙将被暂时禁用。
在维护完成之前，将暂时禁止添加IPv6地址。
此维护有资格获得SLA积分吗？
是的，应将SLA积分提供给要求的客户。

请耐心等待直到维护结束。我们也希望您知道，这是我们的首要任务！
