Yev from Backblaze here - with sincere apologies. After we removed the offending code on Sunday night we went into investigation mode and conducted a rca - we wanted to get some kind of blog post out there so that folks could see that we were working and investigating the issue. I will grant you that maybe our initial execution on that was lackluster, but we wanted to make sure we had a better handle on what we were talking about. We've since updated the blog with additional information, you can read those here:
