The Openreach optical network terminal is the quiet boundary between your network and the fibre outside. Its LEDs are limited, but read in the right order they can separate a dead optical link from a router problem before you pick up the phone.
ISP-supplied routers are routinely declared the weak link before any evidence has been collected. This is a repeatable test plan for establishing whether the box in question is genuinely limiting a UK home lab, and for deciding when a replacement can be justified on measured grounds rather than assumption.
Ofcom's One Touch Switch has removed the administrative friction from changing ISP, but none of the technical risk. This is a cutover runbook for home labs and small offices: staged router configurations, TTL planning, port-forward inventories and a rollback path that works whether or not you get an overlap window.
Consolidation among UK altnets is no longer a thought experiment. This contingency plan helps home labs and small offices document contracts, preserve DNS and remote access, and switch providers without taking self-hosted services offline.
Openreach's PSTN withdrawal reaches its hard stop at the end of January 2027, and the lines most likely to be missed are the ones nobody uses daily. This checklist covers how to inventory analogue dependencies, test them with evidence, and keep a working fallback for the morning the copper goes quiet.
Openreach faults rarely announce themselves before a deadline. This guide sets out a credible 5G failover design for a UK home office, from SIM selection and antenna placement to health checks and a sensible bill of materials.
Symmetric and near-symmetric FTTP has quietly removed the upload ceiling that shaped a generation of home lab design. This is a practical audit of the workloads, backup windows, VPN topologies and QoS rules that are still tuned for 20 Mb/s - and how to re-plan them around real upstream capacity.
A full-fibre connection can still leave you without a public IPv4 address, behind two routers, or with IPv6 that works only on some devices. This Daranet guide sets out the checks, workarounds and ISP questions that separate the three problems.
