server issues?

hey guys
for the past two months my profile has not been able to connect to matchmaking as the server is currently unavailable.
i have contacted microsoft to know avail.
i know this is not a problem with my account as i can access other xbox live features for that account, also my online profiles have the ability to see their rank.
this may be a problem with my upstream bandwidth and/or packet loss rates.

does anyone have any solutions to this problem?
they would be greatly appreciated.
thanks

Not trying to sound creeperish, but where do you live? Most of the Oceania region is having difficulties connecting, which is an ISP-related issue.

Also, what’s your internet speed?
