It's the second time I've chosen AA now and for good reason. They grok it, they're just totally understanding of how good internet and service should be delivered and they work so hard to get you connected.
I had issues caused by tmy landlord attempting to change the address on the apartment but not working with Openreach to do it properly so I ended up unable to order. AA guided me through the steps needed to get Openreach to fix up the service and I just got installed a day early.
Speeds are as promised and full IPv6.
I've used AA for years in a previous life for ADSL and recently with their L2TP service. I'm so glad to be with them for Fibre now.
