(Important bugs for which we need to find owners or additional help. If known, please include suggested team or knowledge needed to advance the bug.)
- Orange Factor
- Stability
- Other
The Need To Know
(Release and system issues that may impact engineering this week.)
Notices/Schedule (akeybl/lsblakk/bajaj)
- Firefox multiple Betas in one week carries on, FF23.0b4 (Desktop) will ship this afternoon
- Firefox 22 Post-Mortem was held this morning

Build Changes (gps)
(Build changes of which engineers should be aware.)
Upcoming Outages/Upgrades
(System outages/upgrades and tree closures that impact engineering.)
6.5 hour tree closure planned for Saturday, July 13 from 1200 PDT to 1830 PDT. Master tracker is bug 889996.
Summary of work that will be done and the impact:
- Failover of the new Bugzilla environment will be tested between data centers.
- Impact: Bugzilla (bugs.mozilla.org) may experience brief interruptions in service during the window
- Buildbot database failover will be tested.
- Impact: trees will be closed, so no negative impact
- http://build.mozilla.org will move to new releng web cluster
- Impact: may experience a brief interruption in service to build.mozilla.org though none is expected; in addition the trees will be closed so there should be no impact to builds during this time
- Database servers across the infrastructure will have their masters changed in preparation for upgrades
- Impact: These failovers happen in a couple of seconds, some apps may fail queries during this time causing an HTTP 500 error or needing a client refresh
- Backend load balancers in SCL3 will be upgraded from 1g to 10g network connectivity
- Impact: some backend databases may experience a few seconds of service interruption, most of these services only impact developer/releng resources that will already be unavailable during the tree closure
- RelEng firewalls changed to "deny all" for unknown internet traffic (has been allowed & logged).
- Impact: No current tests will be affected (already whitelisted). New tests will be denied access to internet resources, developers will need to coordinate with sheriffs & releng prior to landing.
Key Issues
(Non team specific issues that impact engineering.)
- Shumway (jet)
- Welcome Michael Bebenita, new Engineering Manager for Research Team (Shumway)
- Shumway requires about:config changes to work well. See:
- Demo Videos:
