BBC Radio 3 newsreader Alison Rooper had to revert to using her iPhone to read the news when the phone and computer systems at Television Centre went down.
Rooper, who was due to read her first bulletin at 7am, contacted her colleague Rachel Bulkeley and asked her to send the script through to her iPhone.
"The words were reasonably clear on my iPhone screen," she told the Daily Telegraph "but I tried tipping the phone sideways so that the writing becomes bigger and then I lost the whole sentence.
“You need to read ahead all the time when you are reading out news. I had to tip it back to the right position and just scroll through very quickly with my finger, hoping to God I didn't do something accidentally.”
