@Ryan: mathoverflow.com is supposed to be a redirect to mathoverflow.net, but as Gjergji observed, its DNS record seems not to have been updated.

Gjergji, that's most likely a symptom of your browser caching stored information. mathoverflow.net works fine for me. I believe they changed the DNS address of the site during the power outage. Your browser likely has the old address stored rather than making an attempt to look up the current address.

edit: did you mean to say mathoverflow.net, not mathoverflow.com ? I didn't know mathoverflow.com was in use.

One more thing: The address "mathoverflow.com" still says the site is down, instead of redirecting to the main site for some reason.

I got an update email:

Our New York datacenter is still experiencing power issues. We are in the process of moving the Stack Exchange 1.0 infrastructure to our datacenter in Oregon. Please update your DNS records to point to:

69.59.197.25

It will show a down for maintenance page until we are ready to bring the sites back online later today.

I've updated the DNS records, so we should be back up soonish.

If someone has withdrawal feel free to try the MO archive at ludost.net. The site is slow.

I got the following email from the SE team. Hopefully we'll be back up tomorrow.

As of approximately 8:45AM EDT, all Stack Exchange 1.0 sites have been shut down due to flooding from Hurricane Sandy in our primary datacenter in New York. All servers were shut down preemptively to prevent damage and dataloss in the case of a power failure. No data has been lost, however, we do not have an estimate as to when service will be restored in the datacenter.

If reliable service in the datacenter has not been restored by 12PM ET tomorrow, we have plans to begin moving Stack Exchange 1.0 infrastructure to our secondary datacenter on the West Coast. If this happens, we will need all Stack Exchange 1.0 owners who have their own primary domain (i.e. not hosted at [site].stackexchange.com) to update your DNS records to point to the new datacenter.

We will send an update tomorrow with more information, and apologize for the inconvenience.

There is now (at http://mathoverflow.net) a StackOverflow style out of order message with a link to a blog
entry mentioning that the NYC server farm is going down. I guess calling
StackExchange now would not be productive.

The SE server transfer was for the SE2.0 sites. I suspect that MO was not transferred.

MSE and a few other Stackexchange sites I care to visit are up and running. Only MO is down. Ben, why don't you just send a request to them to check what's going on?

No no no...

SE had a huge server transfer from NYC to whatever two weeks ago, or something like that. It is likely that SE would have been down otherwise.

My guess is hurricane damage. For reasons which are unclear to me, lots of hosting seems to have been based in lower Manhattan, so lots of sites like Buzzfeed and Huffpo went down overnight. Stackexchange in NYC based, so it's not unreasonable.

It may be a downed server, DNS issues, but is unlikely a misconfiguration.
A previous meta thread regarding Application Error seemed to be a result
of issues within the local network, so that is another possibility.

What happened to the main site? It's been offline for a few hours now.
