Domain name registrar is DOWN

My spin:If you have visited over the past few hours, as of 4:45pm EST you’ll find the following text:
“We’re performing system upgrades that require us to take this site down temporarily. We’ll be back up and running in about an hour, though, so check back! You’ll have a faster, more secure, higher capacity site to enjoy when you do!”

Well it’s been far longer than an hour…I hope this is not a sign of’s demise….
