(Burbon system -> One of regulation systems against vandals that kicks out IP address to .htacess deny status temporary(2 hours) when it does too many requests in a specfied time(10 min) to a server.)
The reason: bbspink servers, unlike other 2ch servers, now passes host names instead of IP address to the burbon systems. (after around the time >>191-193) [The cause may be HostNameLookup of httped.conf value on bbspink servers are changed from Off to On] It makes whole burbon system to unstable status so they decided to disconnect bbspink servers from the burbon system.
