On the topic rather than grammar still lots going on with network upgrades and Brsk integration.
I experienced higher latency on 8G for weeks while being migrated to new network. Similar increase to those people were complaining about. Wasn't ideal but even at £99 a month it remains a shared, best effort service. There was no noticeable impact to responsiveness or throughput only latency.
God help them when a fibre cut or router outage sends them to their backup BNG again.
