So on my self-hosted site, I have the plugin Limit Login Attempts http://wordpress.org/extend/plugins/limit-login-attempts/ installed on my site and I just got notification that two attempts have been made to gain entry into my site. When I get these messages it shows the ip addresses and I usually check out the ip addresses to see where they are coming from and if I need to ban the ip address from my network. When I checked the two recent ones, they said that it was a dedicated ip address belonging to the Automattic. I find this very odd because normally it is from overseas from hacking attempts and I just ban them from my entire system.
I was wondering if anyone else has had this problem and I wouldn't mind hearing from someone from Automattic about this situation.
