We are facing a huge SYN TCP DDOS attack which causes the server to crash, this leads to item duplication by the fact our database server and the turbo host server is no longer communicating with each other and 500+ characters cannot saved, by this fault we are forced to roll back the server from our latest backup to avoid this thing to happen. No worries that this roll back is just a half day.
The good news is that we are moving to a datacenter that can deal with this attack and the latest date they can have the server for us is on the 22'th of July.
At the moment of waiting, I will still try to tweak the protection of our firewall.
My apologies for the inconvenience
