Bloglines went down. They had some problems with the database at first. They said that no data was lost, but some people just couldn’t login (like yours truly). They than returned back online. After a few hours they posted another notice saying that they need to replace some hardware which will cause another downtime. It looks like that “another downtime” had started a few minutes ago.
The good news are that Bloglines provides the way of exporting subscriptions into OPML files. The bad thing is that I remembered to do so when they went down. Thus, as you can see, my blogroll is not functional currently.
