Illinois is considered both midwest and central, however I was referencing what time zone the servers use based on their location but it's not a big deal.
Back to the original question of the thread, there's nothing more bZ can do in regard to the lag or stuttering. It'd be our hosting provider that has the issues with attacks and packet loss. Banzore has no access to the backend network infrastructure that the servers are hosted on, nor can we make any adjustments. Also due to EA legal agreements, we cannot host BF4 servers ourselves, we have to rent from an approved provider, no exceptions. As was mentioned above, we upgraded the CPU on the main server that hosts 1-6 from a 2288G to an AMD 5950x processor which did improve some performance however the above issues are not directly hardware related.
