Los Angeles-based Geni, the online family tree and genealogy site, suffered an unexpected outage over the weekend, the firm reported Monday evening. The firm said it was down for more than 48 hours over the past weekend, due to an issue with the firm's database software. Geni said that it had an issue with its PostgreSQL database, which it says it is investigating. The firm said it did not lose any data, but is restoring the full database, which is what caused the long term downtime, and also explained that it will be offering up an additional week of service to its Pro users. Geni is venture backed by Charles River Ventures and the Founders Fund.
