不知道使用JustHost主机的用户在前几天是否收到一封邮件，是有关于JustHost的主机服务器的维护通知。通知全文如下：
Dear Sir/Madam,
Tomorrow night, beginning between the hours of 8 PM – 4 AM MST, we will be performing a kernel update on your server. We estimate the outage to be approximately 15-30 minutes. During this time, your email, website and account will not be accessible. This updated kernel brings further enhancements and fixes in all aspects of the kernel, the integral part of which the rest of the Operating System relies upon.
We apologize that we cannot give you an exact time-frame between these 8 hours as to when you will experience the downtime due to the number of additional servers we will be performing this update on as well.
Should you have any questions or concerns regarding this planned outage, please contact support.

虽然这封邮件已经有几天的时间了，但是拿出来跟大家说一说，JustHost会不时为主机服务器进行例行的维护，这包括硬件更换或者系统升级。有时候某些无法避免的会造成主机服务器暂时下线。如果JustHost必须执行这类维护时，JustHost会实现通过邮件通知受影响的站长。JustHost会说明什么时候进行维护和维护的原因，而且也会说明维护所造成的估计下线时间（比如说，下线时间约为15-30分钟），让站长提前了解网站可能受到影响的原因。
