If you're not directly affected and haven't heard the cries of agony of the tagging geeks (such as myself), you're among the few who haven't noticed that del.icio.us is down. The social bookmarking service's datacenter experienced a power failure last Wednesday and had been running sketchily up until yesterday, when it went down for "emergency maintenance." The power failure, it turns out, caused some RAID corruption. The good news is that no data has been lost; the bad is that a day later it's still down. In his blog entry understatedly titled "continued hiccups" del.icio.us daddy Joshua Schachter says that databases are being reindexed and for us to "hang in there." For how long is anybody's guess, but if it's not fixed today there may be rioting.
