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.
March 2000 did not maintain as good performance than February. Still there are some excellent performances namely from PSInet-UK, Nildram, UUnet-UK and Netcom-UK.
We've seen important performance increase from U-Net and Freedmo2surf (after 2 rather poor months).
On the wrong side of the slope quite a few operators have important decreases such as Colt-UK, Inweb, Intensive and Cable-Internet. Other operators loose less ground: INSnet-EU, BT-UK, CWCI and Cerbernet.
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.
Nothing special.
