FYI: SOFT tree close for TCW Scheduled Tree Closing Maintenance Window 2016-11-19 07:00a PST 5 hours

[Hal Wine]

The tree closing this weekend will be a SOFT CLOSE -- there will be period of time where new commits to hg.mozilla.org will be disabled, but the rest of the automation infrastructure will be operational. Some minor work might cause an unlucky job to burn - devs will need to retrigger those jobs.

Thanks to gps & the dev services team for improving our options with hg.mozilla.org, which is what is letting us not have a hard close! \o/

For any other questions or concerns, please contact the MOC as indicated below.

Impact to Users:  

• HG will be hard hatted during a 4 hour window while NFS work is completed starting at 7a,  This will necessitate a hard tree closure.
  

• Patching for Releng DNS, Proxy servers and WebOps servers will occur also starting at 7a.  We expect impact to users to be minimal.

If you have questions about this issue, please email m...@mozilla.com or visit #moc in IRC.  We appreciate your patience while we perform this maintenance work.

Thank you,
