i didn't intentionally block opera. There has been an increasing number of people using the service to update their botnets. Since both mozilla, firefox, and IE have "Mozilla" in the user-agent, I required it, so that their random user-agent won't get through.
The file hosting is down for a few days, because a customer is running a game on that machine and our site puts quite a load on the server, and makes their game lag. I'm installing a new machine soon, tomorrow or saturday i hope, and then it'll be back up. And I'll add opera.
