Certainly A&A have tweaked the numbers but still peak time is still 9-5 Mon-Fri

Consider what bandwidth 1 unit buys on each type of line
20CN Peak: 1.25Gb Off-Peak: 50Gb
21CN Peak 2.5Gb Off-Peak: 50Gb
Be Peak: 10Gb Off-Peak: 50Gb

So even at their closest on Be you still get 5x more bandwidth for yuour unit Off-Peak and on BT lines it buys between 20x and 40x times more bandwidth, so I'd argue we have quite some way to go before the peak times can be said to have changed.

Very true. A&A was the perfect ISP for me prior the change as I worked in an office during the day and had (I think) 125GB per unit on BE in the evenings.

Now I work from home it's not as good but I'd rather have a decent ISP and watch my usage than a [censored] ISP.

In reference to www.aa.net.uk/news-2011-10.html:

We have been traditionally a business ISP with peak usage during the day. Gradually over the last few years that has changed. This means we have a peak usage in the evening and weekends now. Our tariffs need to change to reflect this - encouraging daytime and discouraging evening and weekend usage.

I didn't understand this quote of theirs when I was trying to understand their pricing structure, which does appear to discourage daytime use. But I suspect that they are currently more concerned with controlling demand than in suddenly gaining thousands of extra customers - which could reduce the quality of their service.

Daytime used to be very low allowances and evening weekends much higher.... when I came back I got 8GB per unit for daytime and 125GB per unit for evenings / weekends.

This now 10GB per unit daytime (increase of 25%) and 50GB per unit for evenings and weekends (decrease of 60%)

Granted it's 5x "more expensive" during the day still but they've always had peak during the day as they have a large customer base who are businesses.

I am not a customer so I cant really comment much but when I was on aaisp years ago the impression I got was they would upgrade capacity whenever it was needed, now the last last year or so they seem to be fiddling constantly with their pricing, rebalancing day and night etc. which gives me the impression they trying to equalise the day and night time usage instead of upgrading capacity for the peak usage. In short I wouldnt sign up to aaisp now because they way too unpredictable with what they offer.

I think the rebalancing is more due to changes in the way their customers' data use is balanced than having an overly "make-do-and-mend" attitude to network capacity - with people downloading or streaming more video and other large content off-peak (through services like iPlayer and netflix, or less legitimate means) off-peak traffic relating to personal use is seeing a much higher growth rate than peak traffic which is mainly due to business use. They can't just not react to that sort of change, nor would it make sense commercially to pile more capacity in for those off-peak bursts when that capacity would lie idle most of the time (even in most of the off-peak time). I assume they've considered introducing more differential pricing bands which might help there by spreading the load more evenly, but it would probably be a complication too far IMO: irritating to some existing customers and scaring off potential customers.

I'm told (I forget where I heard this, probably this forum somewhere) that they are currently um-ing and ah-ing about the next stage of capacity upgrades because they at the limit of where current arrangements can practically go and the next step is a major investment with no half-way house. If that step is taken too early they'll lose a pile on running more capacity than is needed for now and would probably have to pass some of that hit on to customers.

In short I wouldn't sign up to aaisp now because they way too unpredictable with what they offer.

On the assumption that my understanding is correct (always a big assumption, I know...) as a current customer I feel quite safe sticking around. They seem to have a handle on where they are going even if they are not sure yet when to charge ahead with certain changes. Their network is stable and not from what I can see showing signs of getting too close to saturation, and the recent change in charging structure was the first in a while (the first since I started considering switching to them over a year ago) so it isn't like they are messing around every month or few, and people who weren't happy were allowed to leave without penalty even if near the start of a 12 month contract.

The upgrade work for the "step-change" has been completed and more capacity to BT 21CN has been ordered.

My understanding of the rebalancing is similar to yours - essentially it was imnplied that the differential between peak and off peak traffic levels had lessened, so the usage parts of the tarrifs were adjusted to reflect this.

In reply to a post by Chrysalis:

now the last last year or so they seem to be fiddling constantly with their pricing, rebalancing day and night etc.

Or it may be because they are preping their centrals for the upgrade to 10Gb.

Upgrading capacity is never a cheap business.

My impression was that they are mainly concentrating on the business daytime traffic and ideally the total capacity is geared to the daytime usage. They'll then tweek the tariffs for the off-peak to try to make the off-peak usage match daytime.

Hi,

I started this thread and can now give my thoughts after one month of use.

I have to say that I had no idea now little 1.25GB per month between 9-6 really is! There are three computers in this household and even severely restricting use during the day I have have used the following (sorry about the formatting) :-

Even though I have only used 20GB this month because I have used 5GB between 9-6 I am way over my allowance.

I can't fault the speeds or the service but this is going to prove to be a very expensive ISP. I live in a small village so am stuck with 20CN.

Plusnet here I come!
