According to an Intology article, nearly 9,000 servers at the facility are currently off line. The Planet engineers are working with the Houston fire department to get clearance to restore emergency backup power and get servers back online.
Since The Planet is a provider of a variety of shared hosting and dedicated server products, I can only imagine the number of websites that may be affected by this outage.

If you’re not a customer, count your blessings and back up your websites. Experiencing a major outage with your hosting provider is not a question of if, but when.
