Research In Motion has reassured users of the BlackBerry e-mail service that none of their messages were lost during a major outage on Monday (11 February).
The incident, the second major outage in a year started at around 3:30 pm Eastern time and lasted for about three hours, causing "intermittent delays" for data services, RIM said in an e-mail statement released hours after normal BlackBerry service had been restored.
"No messages were lost and message queues began to be cleared after normal service levels were restored," RIM said, adding that voice and SMS services operated normally during the outage.
RIM apologised to users affected by the outage, but did not offer an explanation of what happened. The company only said it "continues to focus on providing industry-leading reliability in its products and services."
Yesterday’s outage followed a two-day disruption that took place on 17 and 18 April, 2007. RIM blamed the earlier service disruption on the introduction of a new software routine meant to optimize system cache memory. The problems caused by the introduction of the new routine were exacerbated by the poor performance of back-up systems, RIM said at the time.
After the April 2007 outage, RIM promised that aspects of its testing, monitoring and recovery systems would be enhanced to prevent a recurrence of the incident.
