Hello,
We have to perform some scheduled maintenance of the analytics client servers https://wikitech.wikimedia.org/wiki/Analytics/Systems/Clients, which are named stat100[4-9].
This maintenance requires a reboot of each server, so I'm planning to do this next Monday the 14th of August at approximately 09:00 UTC.
I'll reboot each of the five servers in numeric sequence and I expect the work to take no more than 1 hour in total.
Please do let me know if this will adversely impact your work and I will try my best to work around your requirements.
I'll send another announcement nearer the time, as a reminder to save any work that you may have in progress on these servers.
Kind regards, Ben
