What Alabalcho is going after is possibly a scenic route. 70ms may sound like a low number for normal human experiences, but 70ms is the ping time from the USA to UK. Either the link is congested or it's REALLY long , unless most of that latency is inherent to your connection for some reason, like wifi.
Speedtest is yet another tool to help with testing, but it's not the end-all of tools. You have a 30ms ping to Speedtest, and that's about all it can tell you. It tells you that your connection can be at least that good to other servers if conditions are right.
