Del.icio.us was bought by Yahoo on Dec. 9. Five days later, the data center housing the site (CRNC of Denville, N.J.) suffered a power outage. “Due to the power outage earlier in the week, we are dealing with a number of continued hiccups,” Joshua Schachter of del.icio.us reported Monday on the company’s blog. “We’ve taken everything offline to properly rebuild and restore everything.” Service was restored by Monday evening.

Schachter noted that similar outages would be less likely under the service’s new ownership. “We are obviously not yet on the Yahoo! infrastructure, and this is exactly the kind of stuff they can do a lot better for us (and you,” Schachter wrote.
