Interesting. I thought that WMF had full redundancy among at least two physical sites for tech infrastructure, in case any location went completely offline, such as if there is a fire or flood. Is this not the case, and if so, is full redundancy capability planned?
We only have one primary datacenter right now ("EQIAD" in Ashburn, VA), the others ("ULSFO" in SF, "ESAMS" in Amsterdam) are just cache centers.
There is a new datacenter coming online which will be a full fledged DC along with EQIAD, this one is called CODFW (in Dallas, TX). That DC is not yet operational (machines are still being installed/etc) and after it is there will still be work to make MediaWiki the software fully multidatacenter aware.
