I made the same observations as you did yesterday. When my VSP:s (i have three providers and four numbers, with which Voxalot was registered) refused to appear as registered, even after reregistration attempts, I pressed the Red Button on the Service Status Page. Today, however, I find that the EU server Is still flagged as operational. Reregistration is still ineffektive, though.
And I find deregistered accounts in this thread as well as in another thread about EU Server being down, both threads 1 or 2 years old. I guess I ought to have started a new thread.
My conclusion is that eu.voxalot.com is having problems with registrations, with mine providers; Localphone, Teletek and Bellsip. I just hope that Martin is still around for us. Then we will be fine in a day or so.
EDIT: Problem fixed (by
martin)
