BlackBerry users across Europe, the Middle East and Africa again find themselves without service on Tuesday as a bug that knocked millions of users offline on Monday has seemingly resurfaced. Research In Motion announced early Tuesday morning that BlackBerry service across the EMEA region had been restored, but the Associated Press later reported that Internet and messaging services for users across the region are again offline. The report was later confirmed by several carriers including T-Mobile UK, Vodafone UK and Etisalat in the United Arab Emirates. The cause of the outage is unclear, however a report on Monday attributed the massive service interruption to a bug on a RIM server in England.

UPDATE: RIM has stated that Tuesday’s outage was due to a core switch failure.
