Gmail users worldwide went without Web mail service for several hours early Tuesday morning. Google’s monitoring system indicated that service went down around 9:30 am GMT — 4:30 a.m. on the U.S.’s East Coast and 1:30 a.m. in the Pacific time zone. “If you’ve tried to access your Gmail account today, you are probably aware by now that we’re having some problems. Shortly after … 9:30 a.m. GMT our monitoring systems alerted us that Gmail consumer and businesses accounts worldwide could not get access to their email,” Google’s Acacio Cruz said.
