No problems with the website at all.
I have the same issues as
MNAudiS4 with the timeouts on kvs.unrealnetwork.com
Flightstats shows up OK, it just never shows the results on an availability search. Never had issues with Flightstats either before this.
Maybe some sort of routing failure in certain areas of the internet. If it is working for you, I'll wait a bit and see if it clears up for me.
I am at work. I'll see how it works when I get home later on today.
