I don't do much web development...but when I do, I use jquery. Seriously, that's a well-known tool, how or why would they block it? Ah, checked the linked site:
Update 5:30pm Our enquiry with Sky has elicited a response "“JQuery was temporary blocked this morning having been misclassified. Our review process kicked in shortly afterwards and the site was unblocked just over an hour later."
But hey, no biggie, right? I'm afraid this is where my trollishness takes over, at least in terms of dealing with Corporations. If they have an outage for undisclosed reasons, or reasons I don't find sufficient, they get a bill of some sort. It may not be a bill for much, and nobody has ever paid up (although I've gotten some good responses here and there in return), but I figure the first moment I miss a payment or otherwise don't meet their requirements they're sure to bill me. Quid pro quo.
