The Minecraft skin server is online for about a minute, and then goes offline the next for about an hour. This can be seen in my sig. Anybody know the problem, or is a fix being sent out by Mojang? Does Mojang even know about this?
The signature can occasionally be a little delayed, although it doesn't seem to be the case with this. I presume they know, considering that half of the Minecraft community have laughed at them for it in the past.
