I got this email today.
I am very grateful for this kind of dedication.
I wanted to let you know about something we discovered a few days ago. There was a great deal of traffic to your site, resulting in a total of 37GB worth of traffic to your site for the month. We investigated, and discovered that it was illegitimate traffic caused by bots (we believe). We took corrective measures to block that traffic in future via a firewall rule.
As you would have had no way of knowing that it was happening unless you were monitoring your webalizer stats actively, we are not billing you for that traffic. Further, we'll keep an eye on it to make sure that it doesn't happen again.
