Submission + - Avaaz Trans-Pacific Partnership Agreement petition sabotaged? (avaaz.org) 1
Last night (GMT) it had just under 800,000 signatures of the 1 million target. Today the page was listed as not found until about 3pm GMT, when it returned, but at the time of writing it still lists 0 signatures, with an undefined target.
There has been no word from Avaaz as of yet as to what has actually caused this problem, but it does appear to have been the only petition that was affected.
