One more thing to check, turn on the guitar amplifier... also dead. Aha! Now we're getting somewhere. The odds of both appliances conking out simultaneously are incredibly low, so it must be the outlet they're plugged into. Strange that nothing else in the apartment seems affected. It's not as if I tripped a breaker or blew a fuse.
My landlord seems equally confused, but gave me an extension cord so I could use a different outlet. Good news, my kegerator is still running and once again pours as normal. Crisis averted.
