Excessive number of "build thread" photos, perhaps?
No, its not that. Wish it were that simple.
Search engines around the world are crawling sites to index what is on them. It has gotten so pervasive that total bandwidth has gone from about 1 GB/month to 9GB/month in the course of 12 months. And, Leonard has to pay for that.
Based on some info that Leonard got yesterday, we instituted some changes, and it looks as if the bandwidth usage has dropped off exponentially, albeit the outage today. The outage was actually my fault, as we had to make some changes that did not reflect properly in the configuration file. Simple fix, and all seems to be well. We will see if the changes limiting search engine bots gets the desired results.
