For some reason, their network seem to be very unstable these days. Their servers are great, but their network line went down for the whole night last night. Now it's doing it again. They didn't reply to my emails.
Why don't you call them up and look as what is going on over there. This might be some sort of server migration or might be some network problem or some thing else. If this may be the case then they might have intimated to you.
But it will all be understood only if you get in touch with the company directly.
