Check Point Software’s site was down for 23 minutes from 8:07 to 8:30 a.m. EDT on Monday. Site was down because the domain registration expired, company says. Company says it was because domain host sent renewal notice to wrong email address at Check Point. “There was no security issue whatsoever,” company says in a statement posted on The Register. The error caused changes to DNS servers in DNS servers around the Internet, so it took a while for the correct domain to propagate.”]
