Online horse betting site Xpressbet.com was knocked offline this weekend following a “sophisticated, malicious” distributed denial of service (DDOS) attack.

The Stronach Group-owned advance deposit wagering site posted a notice on Monday explaining why both its online and telephone operations had been out of commission for a couple hours on Saturday. The company reassured customers that their personal data was not impacted by the attack.

The notice lost a few points by classifying DDOS attacks as “a form of cyberterrorism,” which gives these digital extortionists a little more notoriety than they deserve. It’s not really on the scale of blowing up Syrian antiquities, now is it?

Xpressbet noted that it and other ADW firms “have received several such attacks in the past few months, the majority of which were mitigated quickly and without interruption to your wagering experience.” Betfair US’ ADW site TVG also experienced some digital downtime on Saturday, causing hassles for bettors trying to put money on the day’s Pacific Classic and other high-profile races.
