* <b>SCL3/SJC1:</b> We are in the middle of a massive data center move from one of our original data centers, SJC1 to our other data centers. Contractually, this move has to be completed in the middle of the quarter and comprises roughly 1300 servers and virtual machines. While migration work has been going on for a year now to get websites and services out of there in advance of this move, some services are hanging on to the end and may require downtime to get them physically moved (or virtually migrated) to their new home. Please be patient with us as this move takes our resources away from other projects, and as some of these services incur downtime for their move. | * <b>SCL3/SJC1:</b> We are in the middle of a massive data center move from one of our original data centers, SJC1 to our other data centers.

* | * Completed Zimbra migration to HCI. All @mozilla.com & @mozillafoundation.org email accounts are on a new Zimbra infrastructure (and the migration happened with no impact to you!). See http://blog.mozilla.com/it/2012/04/06/re-imagining-zimbra-email-at-mozilla/ | ||
* | * Turned up hundreds of new systems (more than I can collectively count amongst all teams in IT). For example, 128 nodes with new Sandy Bridge Xeon procs have been deployed to the SCL3 data center, and 64 to the PHX1 data center. | ||
* We replaced the NIC cards in our PHX1 load balancers this week with new vendor-recommended cards to overcome problems that have plagued us for months. So far, we have not had any lb-related problems in PHX1. However, part of this success is due to moving the load of Addons version checking and about:home snippets to a new set of Netscaler load balancers which handle the heavy-loaded sites better but don't provide some of the features we enjoy out of our Stingray load balancers. | * Zeus NIC cards (PHX1).
