UPS Says Domain Registration Firm Unable to Provide Access - San Francisco Chronicle United Parcel Service Inc., the world's largest provider of package deliveries, said the company that handles its domain registration wasn't able to provide access to its website for some customers. "UPS.com has not been hacked, and no customer data has been compromised," Susan Rosenberg, a spokeswoman for Atlanta- based UPS, said in an e-mailed statement yesterday. "A fix is in place, and we expect access to UPS.com to resume to impacted customers within a couple of hours." Hackers changed so-called Domain Name System records without breaching the websites themselves, according to Sophos. Consequently, users were taken to a third-party website, the security company said.
