Yep, we had a URL problem earlier today.
Short answer is that the problem has been indetified and all should be corrected in a few days
Long answer for those who are technically minded (and I know thats quite a few!):
We use vbSEO to reformat our URLs into more Search Engine friendly URLs. This morning I noticed that the URLs were incorrectly formatted. I'm really not sure what caused the problem - I know for a fact that thinks were fine on Saturday and (as far as I know) there were no system or configuration changes over the week-end. The problem was corrected about 3 hours ago - the URLs are now the same as they were before.
But during the period when the URLs were incorrectly formated, Googfle must have indexed the site and now have the incorect URLs in its index. This is annoying but should self-correct with the next Google index. Please let me know if the problem persists in a few days.
Now to figure out what caused the problem in the first place :evil:
