I don't think it should be quite as far as thanking him for the downtime. Regardless of whether it was caused by him or not based on server issues or planned maintenance downtime. If that happened to a website like google, I don't think people would thank google for having their search engine down, even if it was just for 5 minutes. It's common for people to take for granted that the site is up most of the time, but that's what all webmasters strive for; A maximum uptime.
