29 months after first BDUK cabinet, North Yorkshire completes
Wednesday 27 May 2015 19:23:37 by Andrew Ferguson

North Yorkshire is a better place to live and work than it used to be before the BDUK roll-outs, the enabling of the 1000th cabinet via the Superfast North Yorkshire has been celebrated in Masham. The projects goal was to get fibre based broadband to 90% of North Yorkshire and our own figures show they have reached 88.7% as of 24th May 2015, there are a few more cabinets to process in the figures which will boost it closer to the 90%.

The more contentious area is how much superfast broadband is now available, our calculations suggest it is 73% currently, but this is for a minimum speed of 30 Mbps and the project is suggesting a figure of 86% at 24 Mbps and faster. The difference beyond there will mostly be down to pessimistic projections from ourselves, and maybe heady optimism from Superfast North Yorkshire (as a guide when we have manually checked our estimates against sample Openreach speeds and speed tests our estimates are towards the low end of the impacted estimate, i.e. often worst case scenario).

The question now is how well will SFNY move forward and how will the speeds of VDSL2 behave in practice, our speed test results for North Yorkshire plotted over the last six years show the progress that has been made and that people are upgrading to the faster products.

The average upload speeds show a corresponding rise in speeds over the last few years. The historical trends show just how much has changed in the last five years, it is easily forgotten that five years ago streaming HD video was much harder than today, both in terms of finding content and your connection supporting it.

Do we know if the 24mbps figure is for data throughput (at the TCP/IP payload level) or at the link level? There's a significant enough difference that it would noticeable change what lines qualify or not.
The other point about actual throughput tests on xDSL is that the results will vary markedly according to the state of domestic wiring. It is surely tricky to disentangle line and domestic wiring issues from a download test.

the speeds i assume are to the NTE in the house / DP at would be at an openreach network level

I'm sure. The point is Thinkbroadband throughput measures provide numbers for how a router is actually connected up, and not how it might if configured optimally. That, and the difference between TCP throughput and line data rates might explain why Thinkbroadband numbers were at the pessimistic end.

There's a case to be made that theoretical speeds are irrelevant; it's actual TCP throughput that matters. But it would be nice to know if different criteria are being used by BDUK and Thinkbroadband as it could help explain the discrepancy.

Note the words manually checked, ie we don't use speed test results as such but they are a good cross check to see if estimates are in the ball park for when doing the full set of estimates across all the cabinets.

The 24 vs 30 Mbps is worth maybe 5% in North Yorks plus need to manually check for the variations like EO and copper rearrangement that can boost coverage a bit too

What do you then mean by manual checks? Do you mean actual measurements you've made using statistics from the router with a known, optimal connection at the property?

I can certainly furnish my stats on an (almost) optimal set-up, but you won't get far using the postcode as a means of estimating line length as it covers everything from 100m to 800m from the cabinet.

We do not go around the country visiting people randomly, so not what you suggest.

Manual checks means, we take our estimate and compare to the Openreach estimates and do this across an area, with 27 million+ premises and ~1.8m postcodes this is obviously something we only do for a handful.

For the most rural postcodes, a postcode can be large and these are rare. Though of course will not feel rare to those living in one like that.

End user speeds are just a final way of seeing if both us and Openreach are being reasonable in the estimate.

I think the reference to 1000 cabinets in the county must include the commercial cabinets.

The original intention for the BDUK project was somewhere in the region of 670 cabinets, so a leap to over 1,000 isn't especially credible.

The commercial rollout was meant to cover (at SF speeds) around 180k premises, while the phase 1 target was around 150k.

Also remember, when calculating the percentage of coverage, that the SFNY project covers two LA's: North Yorkshire and the City of York.

That changes in phase 2 (which isn't quite a fully-fledged SEP project), as York leaves SFNY. It joins SFWY - presumably once their SEP project starts.

I've seen someone state that the 30Mbps target is sync speed, because "it ensures > 24Mbps throughput". Not sure how official that was, though...

I've also seen that the 2Mbps is meant to be TCP throughput, so sync speed would have to be notably higher.
