Servers down at around 3:30 EST?

I sent out a bunch of emails around 3:30 est, but my web server kicked back FAILURE TO CONNECT errors.  I logged into mail.zoho.com, and it crapped out.  I tried from my phone too... the site was down.

Many of my members are reporting that they did not receive the email.  it is not in their spam folder.

Any ideas?  I don't want to resend to everyone as then I may be flagged as spam.

VERY frustrating...
