Just to clarify - there was a bump in traffic (and cost) for some days in May, I've isolated it to being some very old clients that got stuck in an update loop, requesting RAIntegration.dll over and over 4-5 times a second, essentially draining the site of bandwidth. These holes have been patched now (we no longer serve the dll at the root, it's now in /bin), and I'll absorb the additional cost (as it was my mistake), which works out to be around 385gb, costing around $35.14. The total cost for May 2017 looks to be around $143.33, meaning the cost for the server this past month has been $108.19. I'll continue to investigate what else has caused the cost to be more than usual, but keep the estimated server cost at $75 for now.
