That might well be right. I’m a very long time AA user. They are serious about the ‘not being the bottleneck’ thing, so talk to them if you’re getting any performance problems and chastise them suitably.

Managing to maxout the speedtests this morning so I will see how it goes, if things start dropping off again I will raise it with them. As long as it doesn't drop down to < 15Meg with packet loss Tuesday morning at 9am (when businesses return after the bank holiday) as it did with Aquiss/CityFibre I'm doing better 

Looks like level3 routing weird to cogent network.

Does that speed test ISP have any other transit other than cogent or LINX peering?

Not sure about transit arrangements, maybe it will sort itself out.

AAISP changed their routing to lower the latency, and also confirmed the other ISP doesnt peer at LINX.

Also this is affecting other broadband ISP's as well.

Yes can confirm I'm seeing the same so all fixed now.

Speed tests are back up there as well.

Also this is affecting other broadband ISP's as well.

Blinks slowly, wondering if my post above that already showed this has become invisible.

Problem is its not limited to level3, even when routed to Cogent in London their own internal routing is broken.

Its great Andrew was able to manually route around it, but surely the bigger problem is its announcing a bad route to begin with?

[Chrysalis]

Yeah pretty much, AAISP worked around it luckily for AAISP customers, but cogent have a problem to fix, and that UK ISP probably should arrange some LINX peering as well.

Just an update, Andrew from AAISP has picked up this over at Thinkbroadband.  A routing change has been made to IPv4 from 9pm yesterday, which has, at least for me, given me a very good looking BQM.  IPv6 has not been changed as of writing this.  Route is now via lonap, however this has it seems reduced the speed test throughput on the TBB tester on IPv4 tests (now also via lonap on IPv4) in that I only see a flat line of around 350Mbps on single thread tests, typically this was always > 600, IPv6 tests good as normal on TBB going via the original routing.  Just goes to show how things can flip around just by taking a different route.

[Chrysalis]

I found about this today, and IPv6 I see also has the new routing now as well.
