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.

Parece un problema puntual pero sospecho que esto les viene pasando desde hace tiempo: un amigo me comentaba varios casos de conocidos y compañeros suyos que habían perdido TODO su correo-e repentinamente
¿A cuánta gente le tiene que pasar para que dejemos de ver como fiable un servicio? ¿Qué ocurrirá el día que el buscador no funcione? ¿Se pararán muchos trabajos?

We've identified the source of this issue and fixed it. In addition, as with all issues that affect Gmail and our other services, we're conducting a full review of what went wrong and moving quickly to update our internal systems and procedures accordingly.
