Were there any indications from the previous outage if there is a particular website being targeted? Or is it more likely meant to hurt Zerigo as a whole?
I'd love to import my zone files into either (or both) DNSimple and Route53 so I can try switching over.
Now, if I could only get into my Zerigo account to get my zone files. Alas!
UPDATE: Zerigo's dashboard is working for me again as of 6:30 EDT. I'm trying to export my zone files, but I get "Error exporting domain for download. Please wait a few minutes and try again." I'll keep trying.
