No comments on A&A news

Lack of guaranteed speed is probably the same on any other CityFibre reseller [unless the price is adjusted to compensate for a higher committed minimum]; just A&A are open about it!
Probably reflects better on A&A that they tell people about it as others hide the fact?

Another vote here for somehow tying comments to forum accounts, this site suffers from another level of trolling! Some method of notifying or following comments on a news item would be welcome too; difficult to remember to go back and check for replies otherwise.
AAISP do mention a 'committed rate' for their CF based 1Gb and 160Mb services, 70/35 and 10/10 Mb respectively. Obviously quite low but nevertheless its there in black & white (near end of page)

Interesting.

As opposed to a like for like (downstream) on Openreach of 195 Mbps and 95 Mbps on equivalent tiers.

They don’t give a committed rate for upstream on Openreach, but given that the US overbooking is a fraction on Openreach as opposed Cityfibre it’s a safe assumption they could easily deliver the speed noted on the tin there over OR glass.

Differences in committed rates may also be due to the backhaul connectivity that A&A have in place with each provider. You’d expect this to even out over time.

Also as CF transition their serving fibre network to XGS from GPON ought to reduce the overbooking constraints on such tiers.

What amuses me is CityFibre advertise a guaranteed committed rate, but the A&A figures suggest the guarantee is essentially a GPON split in 32 (in fact, for the 160Mbps tier, the guaranteed speeds are needlessly even lower!).

Given all the talk on this forum of how statistical contention works out fine in the real world, I find it interestingly that CityFibre aren't willing to guarantee that in the real world, the contention will be lower than the theoretical maximum, on a fully subscribed PON.

I can see why A&A might not want to get in to having links to every CityFibre location, some would be very underused

I wonder if CityFibre do a similar product which includes Scotland(maybe they have one for all Scottish locations, if you have a datacentre in Central belt)
Exactly, the national access product makes sense. It's just weird it doesn't cover Scotland. Especially when, check this out, the product has a PoP in Edinburgh.

That spec sheet doesn't seem to mention it's England only, I wonder if it's planned to be national and they plan to have handover point in Edinburgh - but they aren't quite there yet.
 
CF, OR (consolidating) and VM have centralised nodes
CF proposed footprint in Scotland is currently small
ISPs big or small will only arrange backhaul to areas where they deem it is worth it.
ISPs such as A&A will decide which is the best underlying network to use that provides the likelihood of customers and the required returns. They can even utilise both CF and OR in the same postcodes for different product profiles if they so choose but will get better wholesale deals if they can increase volumes on one of them.
They may decline any part of the country if it is not justifiable.
Larger ISPs have more ability to generate volumes to establish areas.

OR are stronger in Scotland due to current backhaul for FTTC, R100 and current rollout plans.

So your saying probably not worth A&A or CF investing much time and effort to allow the at most couple of hundred customers in a CF area in Scotland who want to join A&A ? I think your right :)

It’s a commercial question for A&A (at any POP location around the country). They have to get the traffic back and it costs them money for the links and backhaul. No free lunch from CF with their national network. The numbers either stack or they don’t. They won’t invest 10K for a handful of users paying fifty quid a month or they wouldn’t be in business very long.

Sure, but to clarify the National Access product only requires one POP:

"interconnecting at one or more CityFibre Fibre Exchanges [...] Once connected to the full fibre national network traffic is routed back to the nearest POP".

Of course, I'm sure the National Access is significantly dearer than the Local Access product. And NA potentially has worse ping times.
