As some of you may have heard, starting this morning (CST), ERCOT, the operator of the power grid in Texas, has ordered utility companies to implement rolling blackouts across the state due to extreme weather conditions.
2 of the 3 WordPress.com data centers are located in Texas – 1 in San Antonio and 1 in Dallas.
The Dallas facility has been operating on generator power since yesterday evening without issue. This morning, the generator in the San Antonio facility suffered a failure that has left us without a long-term backup power supply in that facility.
There have been 2 utility power blackouts in the San Antonio facility this morning, but so far UPS power has kept the servers running. Technicians are on en route to repair the broken generator, but it is possible that there may be another blackout before the repair is complete.
If that happens, it is likely that the servers running WordPress.com in San Antonio will power off.
We are currently preparing for that scenario and doing everything we can to reduce the impact of such a failure, but wanted to let everyone know the current situation.
Here is a link to the Reuters story about the blackouts: http://www.reuters.com/article/2011/02/02/ercot-rollingblackots-idUSN0221428420110202
We'll do our best to keep you informed.
