hi;
We need to close the trees for 10hours on Sunday 21oct2012, from 8am-6pm
PDT, in order to do network upgrades in MTV and SCL1 datacenters. This
downtime is to allow for 8 hours of Ops work, followed by 2 hours of
RelEng spinning systems back up. The scl1 core upgrade is needed in
preparation for the mobile test build out (BUG#799922), but that project
gained momentum faster than we had planned to get the core online. The
MTV upgrades are to help fix some recent treeclosing network stability
issues.
Summary of work planned:
* Bug 800113 - Relocate df302 switch stack
* Bug 795955 - please investigate UPS outage longevity for mtv1
* Bug 798126 - Move ports in 3MDF from Mozilla Guest network to Mozilla
network
* Bug 797587 - Upgrade SCL1 core network
Sorry for the short notice on this, but this work has been on hold for a
couple of weeks while we've been dealing with chemspills recently, and
this gap in the schedule just opened up.
If there are any questions / concerns about this work, please contact me
or email rele...@mozilla.com.
thanks
John.
