At first I thought the same. I went in to edit records, and I hit save. I checked again and it was working. I assumed there was just a delay of a minute or so and that clicking save was a coincidence.
Well even if you switch to a different (working) nameserver, the old nameserver will still be cached all over the place so it will still appear down for many people.
My domain is on v1 now and its still working.
