THE HTTP MASTER SERVER
Notable features include:
- 15 minutes between updates, instead of two
- Servers actually try to register again after srb2.org has gone down
- Changing master servers actually works
srb2.org is slow so you'll have to wait longer than with the old master server. (That's why updates now occur every 15 minutes.) Multithreading registration/updating/unlisting may be easy though.
