Vic,
I have my personal website based there also and found out it had been down since Sunday. I e-mailed Michael Kranitz about the problem and this is what he said:
"Hi Mike,
Although we are the "best" people to contact, we are not entirely sure what is happening. Network Solutions has had trouble resolving the DNS of all rcplanet sites and we are in contact with them.
In the near future, we will be moving all RCPlanet sites (that we purchased several months ago in an acquisition) to a dedicated server that we own instead of a public domain server. Hang in there as we try to hunt this thing down.
Michael"
So that is the extent of it, who knows when they will be back up again.
