Well from my experience last night, the jhb servers were better than the cpt ones. Lots of lag spikes in cpt with mweb isp and IS isp. So its not limited to jhb. But afaik the jhb servers just need a restart and then they appear in the server listing again.
I don't know about this, as the only JHB server I see (or at least, is says JHB when joining) is 141 [TF] Task Force and I get the same ping to it as with the CPT servers, 110ms +. I think they just moved their server to CPT, but forgot to change the location...
if u look down to your feet, u dont lag at all
they should add that tip in loading screen.
