I'm randomly being logged out. This happened with my works computer (randomized IPs or something) but also happens with my home one too.
Is this because my home computer is tripping out without me knowing? It's still horribly intermittent.

DC uses your IP address as security for your session to prevent session hijacking. This means anything causing your IP address to change will log you out.

Unfortunately this will cause problems if your work is using multiple gateways for load balancing or whatever. Also if your home connection is dropped and you re-connect with a new IP this will log you out of DC.
