Howdy all,
I'm going to be making several changes to the backend of Virtualmin.com tonight, which will lead to occasional downtime. It should be very short (20-30 seconds), but will happen several times tonight. Because software.virtualmin.com is running under the same Apache instance (for the time being) it will also be effected, so updates during this time might run into problems. But, it is temporary, and should lead to Virtualmin.com being faster henceforth.
In short, if you run into site problems during the next 4-8 hours, there's no need to report them. I'll know about them, as I'll be poking at the site constantly during that time.
