Given enough computers, anything will happen. Apparently enough bit flips happen in domains (or their DNS resolution) that registering domains one bit away from the most popular ones (e.g. something like gnogle.com for google.com) might be worth it for bad actors. There was a story a few years ago, but I can't find it right now; perhaps someone will link it.

It's "HN-likely" which translates to "almost never" in reality.
