Unfortunately our anonymous CVS service (at Sourceforge) is currently down, which may impact administrators using CVS to maintain their Moodle sites. (Development access is unaffected).
Sourceforge have told us they switched it off due to very high loads on that server - this may be due to our growing number of users but it may just be a rampant process somewhere. We're still working it out with them.
In the meantime we're working on a CVS mirror just in case the Sourceforge service doesn't come back up.
For full details and updates, you can watch MDLSITE-182 in the Moodle tracker.
The mirrors have started becoming available.
See http://docs.moodle.org/en/CVS_for_Administrators for details on how to access them.
