"It started out with an HTTP time-out error, meaning the server responded very slow and was unable to send the entire HTTP page within the 30 second limit. Then it switched to a 404, page couldn't be found error," said AlertBot's Justin Noll. He added that the daylight timeframe—which makes attributing this incident to planned maintenance unlikely—was "a bad time for it to happen."
