There you are your answer:
Download limitations and banning
In a nutshell
Download only one file at a time. Do not use download boosters such as Download Accelerator. Else you will get temporarily banned.
Why the banning?
Our bandwidth is not infinite. At all times, there are roughly 250-500 file transfers going on simultaneously. Even though we have over 5 Mbit/s dedicated for this, you can easily calculate the average download speed per person. It isn't too high.
If everyone downloads many files at the same time, everyone's download speed would be worse. In addition, since every file download requires one server process, our hardware requirements would be multiplied.
We took years to collect these underdogs, surely you can have patience too? Greediness won't help downloads go any faster, and you are hurting other people's speeds as well.
What triggers the ban and when is it removed?
Every minute, a monitor program checks how many file transfer connections have been initiated from the same IP address. If there are many of them, all of them will be killed, and that IP address will be blocked (firewalled out) from downloading. The rest of the site works fine.
If you get banned, all of your existing downloads time out and are left unfinished. The download page will also tell you about this when you try to download something next time. It will also tell you how many transfers were going on at the time of the ban.
Be warned that even a very small file can trigger the ban. That includes text manuals, walkthroughs, and other non-game files.
Also, browsing the files and marking them to be downloaded later with a download manager while transferring will sometimes trigger a ban.
If you are using a WWW proxy (whether you know it or not-- ask your ISP for more details), our server sees multiple connections originating from behind that proxy as coming from the same computer. Therefore, sometimes false alarms happen. Certain big ISP's force you to use transparent proxies. A good example of these is British Telecom.
All bans are removed automatically with certain intervals. More of these below.
How long do the bans last?
There are three kinds of bans:
up to 3 hours for downloading 2 files
up to 24 hours for downloading 3-5 files
up to a week for downloading 6+ files
The intention of the first ban is to wake people up, to make them realize what they're doing. The others also include a certain punitive effect for excessive greediness as these should not happen by mistake.
What should I do to do it "right"?
Only download one file at a time. You may use (and it is recommended, for resuming) download managers such as Go!Zilla and GetRight, but make sure that they're not working in an accelerated mode (ie. splitting one file to multiple transfers, simultaneously).
Important note: You need to set referer information for this site in your download manager to "http://www.the-underdogs.org/downloadfile.php" - please check documentation that comes with your manager on how to do this. If you are using GetRight, make sure to download and install the "GetRight Referer Manager" from their add-ons download page. This add-on will allow you to enter the correct referrer information manually.
If you're using a proxy, disable it for files.the-underdogs.org. For example, in Netscape, this can be done by entering files.the-underdogs.org to No proxy for setting.
Always use the default download method (in downloadfile.php) if at all possible. This way you don't get banned through no fault of your own.
What should I NOT do?
Some shareware download managers (at least Download Accelerator, JetCar and NetSonic have been reported) split one download to many (e.g. four) to speed it up. You should not use them to download files from our site.
