A massive power failure in Northern Virginia, associated with violent summer storms, caused the Amazon Cloud to hiccup, throwing thousands of systems offline for an extended period. Hundreds of systems were affected, including QRZ. This outage did not affect our servers but did cause a complete database failure. After waiting all night for Amazon to restore our data, we took the bold step this morning to restore from an automated backup. At this point in time we're not sure what data was lost, if any, but there is a possibility that some material may have been dropped. To the best of our knowledge, the our callsign database did not lose any data. Candidates for data loss include parts of our Forums, however this has not been confirmed. We appreciate your patience as this has been a nerve wracking 12 hours, and a sleepless night here at QRZ HQ.
