We are pleased to announce that we will not stop and start your servers this Wednesday, December 21st, between 6:00 AM and 9:00 AM UTC (i.e. 10:00 PM PST on Tuesday December 20, 2016, and 1:00 AM PST on Wednesday December 21, 2016).
Our maintenance operation was designed to address a vulnerability in the Xen virtualization software. To respond, we decided to upgrade the Xen software and take advantage of the features of the new version, to allow you to gain performance and avoid these types of maintenance operations in the future.
However, many of you have contacted us to ask us to change our approach. We started by adjusting the schedule, but it was not enough for many of you.
As a result, we have investigated alternative solutions and we will not stop and start your servers.
We've contacted all affected customers via email. Thank you very much for your feedback on this matter.
