To my knowledge, there isn’t a hard cap on bandwidth. But there may be hidden limits that I don’t know about. I’ve never seen an account get taken down because they hit X amount of data transferred at a certain time.
That said, there is a limit of 50,000 hits per day and, a file size limit of 10 MB and a system that prevent most automated downloading.
And the key rule underpinning many of these limits still applies: we provide website hosting only. If we see you’re using an abnormal amount of bandwidth and see you’re using your hosting account for file sharing, we’ll put a stop to it.
Most hosting services count bandwidth per month, so I think our bandwidth counter is monthly as well.
But without a limit, it doesn’t really matter of course.
