[Labs-announce] Tools NFS disruptive maintenance scheduled on 11/2 is being postponed to 11/14

[Madhumitha Viswanathan]

Hi all,

Tools is now back to read write, and all of tools should work as expected.
Webservice logs aren't being written to disk currently, and will not be
written for ~12 more hours, while we make sure everything else is working
alright.

The storage infrastructure is brand new, so we recommend being a bit gentle
for the next few days, as we monitor performance and make sure it's all
okay. Do let us know if things aren't working like you'd expect, on
#wikimedia-labs/on list or phabricator.

Thanks for being patient through this long maintenance window!
