I rent a server somewhere out in Canada or so that I'm using to host a website of mine. That website has close to 400,000 pages that I wanted to index today. For that, I wrote a crawler a while back (see JCrawler on Stackoverflow.com). Now, I'm greedy and didn't want it to take too long so I ran multiple threads resulting in some 60+ requests per second from my IP. A couple minutes later, my server locked me out. I can still FTP into it, but I can't HTTP it.

As server administrator or user, do you have any idea how servers usually handle these situations? Is it common to place a permanent or temporary ban on the IP or what is typically done?

Naturally, I'll re-run my software with fewer requests once I'm back on.
