Possibly an outage at that exchange he is on?

What BT fault? We seem to have established that BT Wholesale WBC/WBMC is not affected. Every ISP in the country would have the problem.

Therefore it cannot be TT Business using WBC/WBMC. Which in any case , they simply do not do. It would defeat the whole purpose of their existence.

So in the end we have to agree to disagree and can only take the following from the information shared above, which is:

We still know very little about Pulse8's network and can't be sure of who they use to provide their service, they might use TalkTalk, they could use WBC where TTB LLU isn't available, it could be mixture depending on products..

Pulse8 also seem to release information thats seems to be wildly inaccurate, which isn't too good... but others do that too so

The issue could be anywhere really but one thing for sure is that their is no "BT" fault that should be affecting Professors service unless Pulse8 have been less than honest with him.

Pulse8 also seem to release information thats seems to be wildly inaccurate,

Out of interest what information is that?

As far as im aware going on what Adam told me, Pulse 8 use TTB LLU where possible, but will use the BT network when LLU not available. Everything goes over the TTB network (certainly for me on LLU) as i can see from my traceroutes

I think we have to also take into account that he was having issues before today with his line.

My statement you have quoted was regarding the following quote..

Since about 2:15. Showing as BT core outage if I remember correctly on P8 control panel,or so Adam said on phone.

However as you have said your connection sure used TTB LLU, However I may be wrong but your using ADSL not VDSL and also you said where TTB LLU isn't available BT would be used...

Well it could be a case that even if TTB LLU is physically available at the exchange, it may not be in any order to accept another connection for whatever reason so it is still possible that the connection in questions could be routing via BT Wholesale.

PS. my traceroutes say nothing about using BT's network, but it does!

TT Business is by definition LLU.

TTB is not LLU when it's provisioned via GEA-FTTC.

GEA-FTTC needs backhaul from the exchange handover point and for TTB that will be over the TalkTalk backhaul network that supports the much larger ADSL2+ and business connection options.

Yes. But as I say the GEA-FTTC connection cannot be called LLU. Backhaul is not the local loop.
