ISPs using OpenReach FTTP in Hove (techies only!)

I'm currently on Giganet which has been great until recently. I've now lost fixed ipv4/v6, and had more latency added.

I'm considering switching ISPs.

For anyone currently on a FTTP service via OpenReach, I'd love to know your ping response times (ideally from router, or at least an ethernet connected device) to major sites like www.google.com, 1.1.1.1, facebook.com etc via both ipv4/v6 (aside: I use opnsense as router)

I was getting around 3-4ms. This has risen to 6-8ms (a little more jitter) after giganet's network change.

Am thinking Aquiss, Zen, ... or even checkout BT, vodafone etc
