Wikimedia Moving Main Data Center To Ashburn, Virginia 59
hydrofix writes "The Wikimedia Foundation is preparing for the transition of its main technical operations to a new data center in Ashburn, Virginia. This is intended to improve the technical performance and reliability of all Wikimedia sites, including Wikipedia. The current target windows for the migration are January 22nd, 23rd and 24th, 2013, from 17:00 to 01:00 UTC. Since 2004, Wikimedia sites have been hosted in the main data center in Tampa, Florida, a location chosen for its proximity to Jimmy Wales at the time. In 2009, the Wikimedia Foundation's Technical Operations team started to look for other locations with better network connectivity and more clement weather. Located in the Washington, D.C. metropolitan area, Ashburn offers faster and more reliable connectivity than Tampa, and usually fewer hurricanes."

Since I moved down to NoVA over 2 years ago, I've seen a hurricane larger than Floyd and an earthquake and just missed a massive snow storm. The trees decided to have a massive orgy leading to one of the worse allergy seasons ever and now we've got a pretty bad flu season. Nothing surprises me anymore.

My employer's data center is in Ashburn and when the Derecho event happened, we didn't lose access to our resources. It's a modern data center; reliable backup power was part of the decision to house servers there. Not infallible, but proved itself this time. We have more issues with our ISP having failures and configuration errors.

I've got the distinct impression that most power cuts are a result of problems with the distribution wiring (especially if the local distribution wiring is overhead) on a fairly local level (in britan the 6.6KV, 11KV stuff and the 240/400V low voltage stuff, not sure what typical voltages are for similar systems in america). Afaict the 33KV and up stuff has much greater clearances and is on much strudier supports so it's rarely affected by bad weather even if it's routed overhead (which it usualy is because

No, but Pasco County in the Tampa area is considered one of the highest lightning capitals in the world. During monsoon season hail and dangerous lightning occurs practically every other day. THat can knock out data easily. I would not be surprised if lightning hits around the facility at least 30 or more times for the summer months.
Virginia gets them too but not so much as it is surrounded by warm 80 degree water on one side in the summer, but not 88 degree water on all 3 sides spawning these thunderstorms

It's not just earthquakes. Taking the state as a whole, California is subject to every natural disaster known to man save for volcanic eruptions. Anybody moving facilities there, when the intent is as close to 100% up-time as possible, is bloody freaking nuts.

No, we have volcanoes. See: http://www.nationalatlas.gov/dynamic/dyn_vol-ca.html [nationalatlas.gov]
Just because they haven't been active lately isn't any terribly good guarantee for volcano timescales.
However we are completely lacking in hurricanes, also blizzards (unless you go pretty far up into the mountains), and tornados.
The usual suspects like floods and fires we have, and more than the country's share of earthquakes. Also more than our share of infrastructure issues.

Most lightning maps draw a corridor right up I-4 from Tamps to Orlando. The second-highest probability zone is, well, just about the entire rest of the state. Lightning doesn't occur "every other day" in Summer, it occurs almost every day. People routinely get killed or injured.
Still, we know how to handle lightning and storms that take down power. Data centers with smaller budgets than Google are routinely built with motor-generators, backup batteries, power conditioners, etc., not to mention buildings cap

Lightning (especially Florida lightning -- higher frequency AND higher currents) makes Florida special for two reasons. #1, though we can mitigate power failures, it's not a risk-free operation; increase the rate of power failures, and sooner or later there will be a mistake. #2, if the lightning actually hits your facility all bets are off, and lightning strikes buildings at a decent rate (my parents' house got struck every couple of years when I was a kid -- it was on high ground) and hit my in-laws in

They do maintain servers in other data centers, in Amsterdam and San Francisco, and use them for offsite backups and read-only Squid caches. They don't live-replicate DBs to them, though, I believe due to the decreased normal-case reliability and performance that you get when trying to replicate DB servers between data centers on different continents. The architecture of centralized DB with worldwide caches performs a lot better and more reliably. But if the VA servers were offline for an extended period of time, they could fail over to the Amsterdam cluster.

I think they do replicate DBs to Florida (the former main data center), because they wrote it's a hot failover [wikimedia.org]. The other data centers are just caches, because that's most of the requests.
Virginia has had 90% of all requests anyway already, they are serving bits.wikimedia.org (JS, CSS, ...), upload.wikimedia.org (images and media) and I guess also Squid+Varnish.
