Our 10MB line is borderline useless at the moment. We have no shaping applied but we're downloading at a max of 31Kbps? That's not what we're paying for...really annoyed.
Can you give me some more info to go on here. Is it just downloads going slow - is everything slow? Slow speedtests, etc.
Also, can you run a traceroute so we can check latency?
Drop me a PM so we can test further
