Sorry for the vagueness of this report.

What I find is that after some time passes, my DNS stops working for *certain* mozilla.org hosts, but continues to work for non mozilla.org hosts. 

For example, bugzilla.mozilla.org in particular is a problem. If I disconnect and reconnect the VPN, that seems to repair the issue for a period of time.
Hi Selena! I feel like I might have seen this problem before with regards to certain Linux distributions... unfortunately I don't think it was ever resolved, but I'm happy to try again. Which dist / version are you on, and when DNS fails, have you tried sending queries directly to one of our main DNS servers? Next time you see this happen, try: host hostname.that.fails.to.resolve 10.22.75.40 and show me the output.

LOL  Bugzilla doesn't like the unicode in my prompt ;)

Here's my config:

Planning to add "reneg-sec=0" in there and see if that fixes anything!
