Why? Is this happening because they have both mw2 and mw3 servers opened?

hes not the only one with this weird problem

after coming in iw5 i got like LOL pings

in bulgarian Xm servers < my local server i got like 80-100-40

and there is some weird LAG glitches

when i collect data ill will create full topic + video

and he host on my internet provider

in teknoshits i got like 30-40 lag for example :idea: < Example

I'm having the issue as well. I thought at first it was just me . I checked everything . Everything that could be taken internet is going good . I tryed IW4M low ping almost no lagg from the server of the same people I play on IW5M. But no matter what there is high pings and lagg spikes.
