Hello,
I need to schedule a maintenance window to reboot our three dbstore
servers in order to pick up a new kernel version. These servers are
dbstore100[3,5,7]
Together these servers host the analytics-mysql service:

Ideally, I would like to reboot both of these tomorrow, *July the 7th
between 09:00 UTC and 10:00 UTC*.
During this hour's maintenance window, access to the various sections
and shards will be intermittent, as the three servers hosting them are
rebooted.

Note that this maintenance does not affect the Wikireplica databases,
available to Toolforge and Cloud Services:
https://wikitech.wikimedia.org/wiki/Help:Toolforge/Database
Please let me know if this maintenance window is too soon and would
cause you inconvenience.
If this is the case, then I will then look to push back back the date of
the reboots to accommodate your needs.
Likewise, if you have any questions, please don't hesitate to let me know.
Kind regards,
Ben
