DowntimeDetector is a bot for website DowntimeDetector. This is a fun little website with just a single page, containing the text: Is # down for everyone or just me. Users can enter a domain and the sites checks if the domain is still up. Clicking on [Or just me] results in a second page (www.isup.me), with exactly the same functionality. Although the site seems harmless and simple, it is unknown what the bot exactly does, since immediate downtime detection doesn't require a crawler. After checking whether a domain is down or not, users are presented with advertisements.
