KCOM has finished a fibre overbuild that clears a long-standing backhaul bottleneck at Bridlington exchange, letting east Yorkshire customers on its Lightstream expansion network reach advertised gigabit sync rates without evening collapse into Hull core routes. Engineers re-homed aggregation from legacy copper-fed cabinets to a dedicated 100Gbit/s ring that bypasses the exchange’s congested northbound link—an fix holiday lets and GP surgeries had chased since the seaside town’s full-fibre phase completed on paper in 2021.

Where the choke lived

Bridlington’s Phase 4 rollout marked 16,589 properties “complete” on KCOM’s wholesale map, yet wholesale ISP partners reported asymmetric evening slowdowns: downstream burst fine, upstream and latency jittered when traffic hairpinned through Hull. The culprit was not last-mile GPON but a single 10Gbit/s backhaul span shared with residual copper DSL clusters still homed on the exchange.

KCOM’s network operations team described the overbuild as “double-ringed” east—new duct into Bempton Lane cabinets, then south into a Selby-adjacent hub that already fed Hornsea. That topology keeps Bridlington traffic off the Hull inner core except for peering breakouts, shaving milliseconds for cloud VoIP phones tourism businesses run.

Who feels the difference

East Riding Council’s digital inclusion officers flagged Bridlington library’s homework clubs and coastal care homes as beneficiaries; both saw speed tests jump once the ring went live in a staged window Thursday night. GP surgeries on Lightstream 900 plans reported stable video triage sessions—previously nurses rebooted routers when Hull backhaul saturated.

Wholesale ENNI customers buying 10Gbit/s spokes into Bridlington can now provision without “best effort” caveats in KCOM’s data sheet. ISPreview readers in Bridlington posted tracert screenshots showing paths staying local past Flamborough rather than dog-legging via HU1.

Investment framing

KCOM’s £100m expansion programme always promised full fibre “all the way,” but backhaul upgrades lagged front-door installs—a pattern familiar in other alt-nets. CEO Dale Raneberg’s 2021 press release celebrated take-up; Friday’s engineering note quietly closes the loop on a ticket partners logged for eighteen months.

Hull’s historic monopoly footprint still funds the expansion areas; Innovation Observatory’s £469m regional productivity estimate assumed reliable sync, not headline availability maps alone. Bridlington’s tourism pitch—“open for business” with full fibre—now matches traceroute reality.

Competitive and regulatory backdrop

Openreach FTTP appears on parts of Bridlington’s fringe; KCOM’s fix strengthens retention where it already owns the drop. Ofcom’s wholesale reporting treats KCOM as a distinct geographic monopoly outside Hull; no pricing changes were announced with the overbuild, though business tariffs referencing “uncontended backhaul” get a footnote update Monday.

CityFibre and other builders are absent in the core resort; the bottleneck story is intra-KCOM. Resellers asked whether Selby and Hornsea rings get the same surgery—KCOM said Bridlington was the worst east-coast choke and Selby is next on the Q4 list.

Engineering detail for partners

The new ring uses existing SRN-adjacent duct where possible, avoiding summer roadworks on the A165. Splice teams worked overnight to minimise disconnects; consumer impact averaged four minutes per cabinet according to status-page logs. Monitoring now splits Bridlington KPIs from Hull core dashboards so NOC staff spot local regressions faster.

Legacy copper backhaul remains for stragglers not yet migrated to Lightstream; those flows still touch the old 10Gbit/s span but represent under eight percent of evening utilisation post-migration push. KCOM aims to retire that span in 2027 when copper switch-off milestones hit.

What customers should verify

Lightstream subscribers should rerun speed tests after router reboot—PPPoE sessions stuck on pre-maintenance BRAS groups will not see gains until reconnect. Businesses with static IPs need no renumbering; wholesale partners must update internal capacity plans now that 10Gbit/s ENNI spokes are credible for Bridlington sites. KCOM’s status page will flag any rollback windows if Selby ring work shares splice crews in October.

For east Yorkshire coastal traders, the overbuild is the difference between marketing gigabit and delivering it when August crowds upload beach drone footage. KCOM’s exchange bottleneck was invisible on coverage maps but loud in support tickets; clearing it is the kind of unglamorous fibre work that actually keeps a holiday town’s tills online.
