Yes, I know.
The 2 worldspot servers were up and running but the 2 worldspot DNSes (at my provider's) went down.
It should have lasted about 9-10 hours.
I've been alerted by one of my monitors but I could still access the servers. This is why I didn't suspect the DNSes until the next morning.
I've now corrected that problem by adding 2 more dns servers located in the states. Now there are 4 DNSes serving the worldspot domain.
There should be no more problems from that point of view.
I am really sorry for the inconvenience, and I'm doing everything to keep the worldspot service reliable.
