The forum and the hosted sites are on different servers...
The faq.astahost.com site is on the same server as the hosted sites.

If you are blocked on one server, the other servers are not informed. If the xisto network goes down for some reason, all of the servers for xisto are affected.

Additionally, the AstaHost and Trap17 forum servers are much less security sensitive. This simply means that it takes longer for those servers to block you than the other servers.

Having said that, in order to protect ALL of the hosted websites, the hosting server is set at a greater security sensitivity than the forum servers so if you make a large number of requests on the hosting server from the same IP address in a very short period of time, you IP will be banned automatically. I know this because it happens to me about three times a year. What is worse, is if your page is loading slowly due to high traffic on the hosting server, you might try to load the same page over and over in a short time to avoid the "timeout" feature in most web browsers. Also note that FTP connections are counted in this issue so if you are updating, creating, or testing something for your website, you are at higher risk of this problem.

So to prevent this:

• Be Patient - If a page is timedout, wait a second before you try again.
• Request Less - If you have more than one page of your website open in your browser windows or tabs, don't try and load / reload more than one of them at a time. multiple requests at the same time is the quickest way to get an IP block since the server thinks you are a bot trying to overwhelm it.
• Set Up A Test Server on your local system to try stuff out on instead of the hosting server. This will save you time since you don't have to upload files to preview them.
• Don't Freak Out - The server has two stages for this security feature. When you put in too many requests, the flood control suspends your IP for a few minutes to deter automated bots that are trying to overwhelm the server. If you continue to flood the server after you get a temporary block, the server gives you a permanent block.

Once you get yourself banned, there is only one way to get it fixed...

Yeah it's working now, it was PeerGuardian blocking it :S, it must have been an update in the lists since I last tried to login to my cPanel, now I just disable it while I'm using it, or shut it off.

I also test everything offline (including php/mysql code and setups) and always advise others to do so as well (it can really save a lot of pain, bandwidth and time).
