SourceForge has been playing with system upgrades again, and in an attempt to debug the failing CIA commits on IRC, I reinstalled the hooks for CDK and Bioclipse, so that now all hooks seem to fail, including the email hook... Apparently, it is a known bug, e.g. see this bug report. I assume SF will fix this soon.
On the bright side, I also noted an updated webpage for SF uptime/problem tracker, where it is also reported that stats are currently down for upgrade. There also has an RSS feed, which I recommend as a good monitoring tool for SF site problems.
