Suppose one in bangalore is using ACT and gets 150-190ms ping to EU servers, can an ACT user in chennai expect the same? Sorry if that made no sense. Also i cant use the Q&A section, so pardon me if this is in the wrong place.
That would depend on how the ACT network routing is set up IMHO. If Chennai is downstream to Bangalore on ACT network, it would take marginally longer for pings to EU servers.
