Something happened at 1and1

This morning, I was having issues with my phone not connecting to the 1and1 exchange server for my domain. It was giving an error, "Waiting for network". Google taught me that there are many reasons for this error and generally resetting does the trick. Naturally, after deleting it from my phone and reentering the information, I am met with the "the server could not be reached" error.

I go to exchange.1and1.com. No response
I go to 1and1.com. No response
I go to admin.1and1.com No reponse.
I call all tech support/billing/sales numbers. All circuits are busy.

My web hosting for this domain seems to still be online, but beyond this, I am clueless!

Edit: Roughly around 1300 CST, things are coming back to life, no explanation yet. I'm still getting old emails trickling through.
