Last week my bandwidth grounded to a halt which is usually the result of someone uploading on my network.

I went to my girlfriend's computer to see if she was syncing with Dropbox or something. Nope. She quit all of her applications just to be sure. Except for a single browser tab opened to a recipe for pita bread.

Yep, turned out that a recipe for pita bread was saturating our router because what looked to be buggy error-handling for ad-related network code. I think her ad-blocker only partially maimed it, so it went apeshit.
