Hi,
On Sunday, 3rd January around 1-2AM UTC, I will be upgrading MySQL on the
database servers. At the same time, the operating system will be upgraded.
Total downtime will be around 30 minutes to upgrade MySQL, and 5 minutes to
upgrade the OS. There should be no user-visible impact from the upgrade.
This issue is being tracked in JIRA as MNT-112.
