DUBAI, United Arab Emirates (CNN) -- Large swathes of Asia, the Middle East and north Africa had their high-technology services crippled Thursday following a widespread Internet failure which brought many businesses to a standstill and left others struggling to cope.

One major telecommunications provider blamed the outage, which started Wednesday, on a major undersea cable failure in the Mediterranean.

An official at Egypt's Ministry of Communications and Information Technology, speaking on condition of anonymity, said it was believed that a boat's anchor may have caused the problems, although this was unconfirmed, AP reported. He added that it might take up to a week to repair the fault.
