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.

Monthly round-trip delay and percentage loss data is available for the last 6 months. Click on the navigation bar to access the detailed monthly statistics, or to view the hourly/daily data for the Munich Node.
