Several news websites went offline yesterday as surfers looked for information on the terror attacks that struck London.
Keynote's data showed a 400 per cent increase in average download times for the sites. The data indicates that web performance started nose-diving shortly after the first explosion at 8:51, and reached its deepest point two hours later.
The sites improved at this point, but performance remained sluggish throughout the day.
Mobile phone networks also suffered temporary access problems.
In addition to traditional media, bloggers rose to the challenge to satisfy the public's hunger for news.
The friends and family hotline for the London explosions is 0870 1566 344.
