接服务商通知，13号到17号升级内存，可能会出现暂时网站无法打开的现象。
We will be upgrading your server (celia) from 4GB to 8GB memory during the week of April 13th to April 17th.
This upgrade will only take around 10 minutes during which your websites will be down. We will be performing these upgrades during off peak hours starting at 1:00am Eastern Time each day; we are aiming to do ten servers per night. We do not currently have a set schedule of which day your server will be upgraded as it is largely dependent on how long it takes to pull the server off the rack, replace it, and so forth.
