[UPDATED 2015 07-22 1905 UTC] The popular QRZ.com website has been undergoing a major upgrade since last Friday, and things are going a bit more slowly than initially anticipated. QRZ.com Founder and President Fred Lloyd, AA7BQ, said the site’s engineers “have encountered some unforeseen problems.”

“What started out as a simple update that went bad is now almost over,” Lloyd announced on the site’s Facebook page early on July 22. “We’ve replaced our forums software and are reconfiguring it for use with QRZ. While we realize that many folks have been concerned, we want to express our sincere thanks to those who have been patient and understanding with us as we work overtime to put the system back online.”

The outage does not affect call sign lookups, logbook, and other site features. Lloyd said QRZ.com is “looking forward to a shiny new user interface and a bunch of new features for our wildly popular Ham Radio Forums.”
