Internet 'down' in Dubai

The internet was 'down' in Dubai for 20 minutes this morning, no YouTube, no blogs, no newspapers, no Facebook, no explanation.  Every website except, interestingly, Bank of America and Citibank seemed to be blocked.  When a site is banned in the UAE the screen on the left appears.  Its Um Saloom from the UAE cartoon series 'Freej' telling you that the site you want is very naughty and that you ain't goin' nowhere.  The lurid pink background is quite a surprise initially but that passes.
