Denial Of Service Attack Update

Dear All,

We were hit with a denial of service (DOS) attack today beginning around June 12th 2019 @ 01:27:51 PM from an IP address registered to "RACKWEB-NET" in Bulgaria.

I was notified about this around June 12th 2019 @ 03:05 PM and did some log file analysis and discovered how the attack was happening and wrote some code to mitigate against the attack.

I think the site was down for about 1 hour and 19 minutes because of the attack.

The code I wrote will filter against these kinds of DOS attacks in the future.

Thank you for your support,

Neo

EDIT: In addition to the PHP changes, I made some changes to the DB configuration as well to help insure this kind of attack cannot succeed in the future.
