Zombo.com stopped Firefox development for a day back in, oh, 2011 or so. Somebody noticed that new tests were failing and the tree ended up being closed for new commits while the problem was investigated. Turns out that a month or so prior someone added a test that loaded zombo.com, and the site had gone down. This may not have been a coincidence, as all the racks of test machines had been running that test nonstop and effectively DDoSing zombo.com for a month. Anyway, that's why the test servers are now firewalled.
