Sky admit it's engineering issues on their core network, relates to the Alcatel Broadband Network Gateways, SR 7750s, they are terminating the PPPoE sessions on I believe.

Except Sky doesn't use PPP on their fibre products. Maybe ETHoA, or IPoA or whatever its called, but you just need a modified DHCP client connected to the Openreach modem, and in your DHCP client options you provide the userid/password pair.

Mmm forgot that part, thank you. Hardware terminating it is the same though, Alcatel SR 7750.

Could be a bug given they don't use PPP. I recall the DHCP bugs in Netgear firmware found on the O2 and BE networks, which probably came to light on the only UK ISP that didn't use PPP

A quick analysis from our speedtests. Slightly odd shape for the Fibre Pro product, wonder if that is showing the problem people are talking about.

What's the X-axis?

As I say its a speed profile, so just all the tests arranged in order of descending speed.

This means if an ISP is running a speed cap e.g. 8Mbps you should see a flatish line at 8 Mbps if lots of people hit it.

So won't the graph just become a 45 degree straight line as more speedtests are done?

Given a big enough distribution yes - but I doubt the UK phonelines are that consistent.

Would it be better to plot the number of speedtests having a particular value on the X axis?
