I had the same problem earlier. Now that the site is back, though, every time I come over here, I get a pop-up from Kaspersky Security that says:

Application Firefox contains link to web page http://.../ads?client=ca-ib_travel_sede_1&output ...used to steal passwords, credit card numbers or other confidential information. Denied.

It still lets me read the threads though. At first I thought it was more of an issue with Firefox, yet when I go to any other website, I don't get that pop-up screen. Only here at Flyertalk.
