The labsdb1001 reboot is happening soon, in ~25 minutes.

labsdb1001.eqiad.wmnet (aka c1.labsdb) will be rebooted at 2017-10-30

Normal usage of the *.labsdb databases should experience only limited
interruption as DNS is changed to point to the labsdb1003.eqiad.wmnet
(aka c3.labsdb). The c1.labsdb service name will *not* be updated
however, so tools hardcoded to that service name will be interrupted
until the reboot is complete.

There is a possibility of catastrophic hardware failure in this
reboot. There will be no way to recover the server or the data it
currently hosts if that happens. Tools that are hosting self-created
data on c1.labsdb *will* lose that data if there is hardware failure.
If you are unsure if your tool is hosting data on c1.labsdb, you can
check at <https://tools.wmflabs.org/tool-db-usage/>.

This reboot is an intermediate step before the complete shutdown of
the server on Wednesday 2017-12-13. See
<https://wikitech.wikimedia.org/wiki/Wiki_Replica_c1_and_c3_shutdown>
for more information.
