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.
The November results are not as good as October ones, despite the removal of BT-BE (worse results of October) and Global-One-BE. They were removed cause their performance was not sufficient to be included in our stats.
Main points this month: KPN-BE and Eunet-BE have gone down. Please also note that PSInet-EU-BE get the lowest overall TBS score because of an excessive amount of unreachability (over 64h aggregated). This is despite the packet loss score which is the lowest of this chart (i.e. the best). As you will notice, we consider that it is useless to have low packet loss if availability is low too in our measurements. This problem was noticed in other countries where PSInet-EU is available too.
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 to comment on.
