Difference between a good and a bad isp

Nowadays is there any decernable network performance between a good and a bad isp when using the Openreach FTTP network?

Historically in the days of adsl I saw quite a bit of discussion in regard to congestion on some isp's back haul connections, however not really heard much nowadays so was wondering if this is no longer an issue?

Nowadays are you just paying for the customer service with a premium ISP? or does the network actually perform better?

Openreach doesn't connect you to the internet, they connect you to the ISP. If the ISP decides to have 5 million customers and only a 10 Mbps connection to the internet, the fastest Openreach connection from the ISP to your home isn't going to make any difference, the internet connection is going to be rubbish.

So yes, worth reading reviews of ISPs and other people's comments on the forums.

What I've learnt from the Zen backhaul issue over the last month is that there is still a massive difference between a good and bad ISP using the Openreach FTTP network.

OK then, perhaps someone would care to list at least some of the better providers for FTTP?

Openreach only control the access network, the tiny section between your home and exchange.
FTTC saw no contention for the vast majority of users between the FTTC DSLAM and the exchange. The rest was down to the ISP.
FTTP is the same. It's extremely unlikely you will see any contention/slow downs caused by the Openreach part of the link.

As others have pointed out the ISP controls everything beyond the exchange.
Whether you are connecting to a server/website 20 miles away, 500 miles away or 5000 miles away it will all go through your ISP. If the ISP are a bottleneck it could affect all traffic.
Your performance will also depend on what transit/peering agreements your ISP has in place for when you leave their network to the wider internet.

A lot of people assume that because it's full fibre then that must mean full speed 24/7 but that's a massive misconception.
Home broadband is a contended product. It's a shared, best efforts endeavour.
The only difference is that the connection speed doesn't degrade/decrease as distance to the exchange increases and latency and reliability should be a bit better.

So does the ISP have to rent a back haul link from every individual FTTP enabled exchange?

That depends...

They may have their own backhaul present (eg. Sky, Vodafone) or use a wholesale provider (eg TalkTalk or BT Wholesale) from the headend/parent exchange back to their own core network.

Interesting stuff.

How many parent / headend exchanges are there?

Yes thoughts on this would be appreciated

Roughly 940 odd nationally...
