ISP - Sky Broadband (Unlimited)
Country - UK

Lag pause 10-20secs/min in the evening and 1-3sec/30sec during the day. Give up trying to contact sky without them telling me its SE problem. Only sky user who reporting this problem and no other isp in uk so I think its most likely certain isp in each country having this problem.

last 4 pages here alone are all from sky only in uk.
