Parts of downtown without power

KTRH-740 is reporting that parts of downtown are without power this morning because of a fire at a power substation.

We're told that the outage has affected the offices of the Chronicle. The Chron.com main page was down earlier, but has now been replaced with a temporary news weblog.

UPDATE (12:42 pm): Chron.com seems to be coming back online, several hours after power was reported to be restored downtown.
