I have 3 sites, two of the 3 are now down covecube.com and stablebit.com It's a simple DNS issue, the sites are accessible from their secondary URLs. Pinging the secondary URL does not return the same IP as pinging the actual domain. Sure enough, when going to the "DNS Manager" in the control panel, the IPs are incorrect. Apparently someone has switched the IPs of these servers and forgot to update DNS. I opened a ticket, so far no response. Correction: I'm not sure that this correlates to w02 and w04, my third site bitflock.com is also on w02 and is fully up, but with a different IP.
Just to clarify, "forgot to update" something is never the cause of an outage. If it was, we would say so. You'll have to trust that when you see a server listed as having an issue in the outages and maintenance forum, that issue wasn't caused because we are idiots. Well, okay, I'm an idiot, but they don't let me touch the servers, you see? Thank you, and happy holidays.
