I miss "bing" which was not a search engine, but a "stochastic bandwidth measurement tool". It could tell you the bandwidth between any two network links regardless of limited bandwidth between you and the targets. I could measure T-3 or OC-48 backbone link speeds while I myself was connected, several hops away, on a 33.6Kbps modem link. It did not last long and it seemed to be abandoned, and popular Linux distros stopped carrying it as a package. I'm not aware of another tool that can perform the same measurements.
