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 table contains the average PoP-to-PoP round-trip delay values (in ms) and percentage loss values for the BT Global Services Barcelona Node between 09 Sep 2010 08:00 GMT and 09 Sep 2010 09:00 GMT.
