Coverage checks and tools

- Run a speed test several times (peak vs off-peak)
- Check postcode-level fibre rollout pages
- Ask neighbours or local groups about real-world speeds
Common migration pitfalls
Timing
Overlap or gaps between service end and new install can cause downtime. Book with cushion days.
