Our IP Performance WWW site contains the results of round-trip
delay and loss measurements which we perform between
key locations on our IP Backbone Network, and to key locations
on the networks of our strategic partners.
Several of the pages on this site are updated hourly and
thus reflect the current state of our network;
other pages are there to provide a more historical view
of the performance of our core network.
|
|
The following tables contain the recent
daily average inter-regional delay values
(in ms) and percentage loss values for the
BT Global Services IP Backbone Network.
