Description of the data collection process here.
Our reliability graphic displays the percentage of packet loss on the left axis (cyan bars) i.e. 100 - packet loss %. On the right axis (blue points) we display the availability percentage i.e. 100 - unreachable % (unreachable result is attained when none of the 15 probe packets are returned). Therefore the longer the bars and the upper the points, the better.
Good performance in December! Noticeable increase for Deutsche-Telekom, IS-Europe, POP and Gigabell. PSInet-EU gets "normal" results in December. We noticed the performance decrease of DFN (partially due to availability problems), Easynet-DE, Regio and Contrib-net.
Global-Access-DE was removed of the chart.
Our roundrip graphic displays the mean roundtrip time in milli-seconds. This graphic should not be read and analysed alone but with the availability chart above. Alone this chart does not mean much.
Good roundtrip for COLT-DE.
