Something is very wrong with Google PageRank checkers

Tonight, 2 of the more popular Google PageRank checkers, namely PRChecker.info and Checkpagerank.com are down for the count.

In fact, going to the root of PRChecker.info (rather than the PageRank page - http://www.prchecker.info/check_page_rank.php, which just comes up as a 404) just brings you to a default Apache Page:

This really sucks, considering that many people that host PageRank checkers on their site actually route through PRChecker.info.

Update: 6/17/07, 12:54pm - PRChecker.info is back online, but Checkpagerank.com is still showing as offline.
