"Virgin posted an apology to its Facebook page..." but they didn't email their customers. After all, the fb adversphere is all that counts...
OK if Vodafone had a Vodafail, what happend to Virgin? A VirginDP'd? And Amaysim was Amayslayed?
These network operators are more screwed up than me: What are the odds it was their core billing or authentication systems not being secure, resilient or redundant.
It probably wasn't even the dodgy traffic management they use to prioritise some customer's traffic over another's.
