What hosts are good for running phpBB forum?

[amseo]

I suggest you hosgator or bodhost. And i have a question from you:
Do you want to install phpBB on a shared hosting or a dedicated server? Suggestions can be different according to your answer.
But if you want a short answer, Hostgator is good for both choices.

That is quite a lot of bandwidth, I doubt many hosts would be able to provide that for you. How many users does your forum currently have? I do not think you are using anywhere near that much bandwidth monthly. If so...that might explain why your website is down...
