Users from your ISP/hosting provider have made excessive requests to this server, so we unfortunately had to disable your access.
If you're running a bot, then you are more than welcome to use our data, but not our web interface. Instead, please clone the underlying Subversion repository, which has the exact same data and is much more efficient to access.
If you're a human, please contact us via email at webmaster@tug.org and we'll happily whitelist you.
