> Check that it's really fixed, check that it's really your fix that fixed it, know that it never just goes away by itself

I wish this were true, and maybe it was in 2004, but when you've got noise coming in from the cloud provider and noise coming in from all of your vendors I think it's actually quite likely that you'll see a failure once and never again.

I know I've fixed things for people without without asking if they ever noticed it was broken, and I'm sure people are doing that to me also.
