Google has issued an apology for its system wide GMail outage for a couple of hours yesterday afternoon.
Many of you had trouble accessing Gmail for a couple of hours this afternoon, and we’re really sorry. The issue was caused by a temporary outage in our contacts system that was preventing Gmail from loading properly. Everything should be back to normal by the time you read this.
Gmail, including the email service provided by Google Apps, is estimated to have about 100 million users. Around 20 million users access GMail each day, and for a few hours yesterday afternoon, they all see the same “Temporary Error (502)” when accessing GMail. The error was first reported by users around 2pm PST, and twitter was storming with complain posts about the email service downtime. Well luckily for us, Google never highlighted in its apology that its GMail service is still under beta, as labelled under the GMail logo.
