BlogRolling

BlogRolling has been taking a dive for the last 24 hours. Now they do not even come up with an error page. I was so happy over the last month with their performance. Hopefully they will soon be able to fix their problems and keep their service free. Does anyone know their status? Are their any other good free services on the net that will do the same thing that Blogrolling does? (an easy way to add link to the sidebar)
