What do you count as a reliable service? I have VirginMedia (and no, I don't work for them or anything else) and in the last decade you can count the number of noticeable outages I've had in the last decade on the fingers of one hand - I'd call that pretty damn reliable.
Chris Addison on Mock the Week summed it up (this is a slight paraphrase) "We have the total knowledge of the Universe at our fingertips which is utterly amazing, but let it go down for five minutes and we're all 'AM I LIVING IN A THIRD WOLD COUNTRY THIS IS OUTRAGEOUS OH MY GOD THE HUMANITY'"
He has a point. We should all know that things can happen to IT systems that you can't plan against - what is most important - and here I will accept the criticism of VM - is communicating with the customers. Having a recorded message on your helpline that tells you to consult a webpage when your internet is out is pretty awful.
