Github pages site size limits?

Related is bandwidth usage (amount of data transferred). There is a limit but it isn't documented. Taken from the GitHub Terms of Service:

If your bandwidth usage significantly exceeds the average bandwidth usage (as determined solely by GitHub) of other GitHub customers, we reserve the right to immediately disable your account or throttle your file hosting until you can reduce your bandwidth consumption.

GitHub now has new policies of a 1GB filesize repository, warnings for pushes of files over 50 MB and complete rejection for fileuploads of 100MB. GitHub warns you when you push a file larger than 50 MB.
