Neat!

Sounds like you've uncovered a bug in 0.1.2.19. I'm guessing you didn't
set your Address line, so Tor is doing its best to guess. And it sounds
like your Tor made a tunnelled connection through 212.112.242.159 to a
directory cache, and then it got suckered into thinking its IP address
had changed.

Can you give me a few more hints? Anything else in the logs? Is this
repeatable? Were you doing anything interesting at the time? Do you run
a hidden service too? Had your relay been running for a long time or
short time before this happened?

Has anybody else here experienced this?
