I was working about 500 m away from the bombs when they went off.
Didn't hear anything directly, but all of the internet suddenly ground to a halt and I remember scrabbling around the various international news sites for clues as to what was going on.

French news sites: There has been a terrorist incident in London; the number of victims is as yet unknown.
German sites: Terrorists have set off bombs on the London Underground; here are some nice pictures of blown-up people from similar incidents to accompany your morning coffee.
Italian sites: Bombs on the Underground in London, at least 80 dead.
British sites: Reports have been coming in of a power cut on the London Underground...

You can understand the approach, of course. Keep people in the dark so they don't panic. Still took me three hours to get home, though.

Not necessarily
As stated above, those were the first official reports, and the British sites will have been hit by the same internet surge you were, possibly meaning they couldnt update the story as quickly due to server load (or the updates hadn't got to the backup ones yet)
