I've been seeing some strange dropouts on my 2degrees connection over the last week, it always happens between 11pm and 12am. Connectivity to everything just dies, and then comes back 3-4 minutes later.
You can see in the traceroutes that a few succeed after a bunch of timeouts, if it's close to the end of the dropout.
Traceroutes just to demonstrate the issue... everything stops (browsing, VPNs, SSH sessions etc)
