Hah i just cancelled it as well. I use to have 600gb last two months of data stored, last two weeks i am at nearly 5tb, thats like 70usd plus 10 usd for the other operations. No real changes on the site to justify the massive jump in data cache.
I bet with the product cancelled it will blow out more, maybe another 20 usd since it uses agregate days which you cannot purge the buckets until they disapear on invoice reset. Basically, we are screwed.
