Nodes Take Over London

Performance & Operations

This week Catchpoint launched 6 new nodes in London, which are connected to 6 consumer ISPs: British Telecom, O2, Virgin Media, TalkTalk, Orange, and Sky. The connections range from ADSL2 to Cable. This deployment brings our coverage in the United Kingdom to 11 nodes (5 Backbones nodes and 6 Last Mile nodes).

I wanted to share with you some interesting data from these 6 consumer internet connections. We monitored the Google Homepage over a two day period, collecting 3640 samples of data. The Median Response time was 290 ms (the time to get the HTML) and the Median Webpage Response was 1,095 ms (loading all the requests to render the webpage)

Web Performance by ISP:

When looking at the data by hour of day, by ISP – an interesting pattern emerges. Virgin Media has performance bottlenecks starting at 2 pm UTC. (It is Cable connection with advertised speed of 100 Mb/s).
