The outages may well be the work he's already doing (or a colleague) upstream.
You appear to already have the new channel plan with 4 possible upstream 6.4MHz RF with 200khz guard bands (24.4, 31.0 , 36.6, 43.2) in space of 3 typical existing centre frequencies (27.4, 35.8, 45.8, ) previously.
Theoretically I think you could get 6 x 6.4MHz x QAM64 channels from 17.8MHz thru 59.8MHz based on those centre frequencies just before replacing legacy 5-55MHz DOCSIS Bidi amps to accommodate the (euro)DOCSIS3.0 (5-85MHz) upstream spec and expanding upstream capacity further.
However VM may be trying to defer replacement amps in order to accommodate wide bandwidth DOCSIS3.1 amps for OFDM with bottom,mid and top band splits. Replacing all UK (or large proportion of legacy Gerold) equipment is not something you leap into without significant planning and you certainly don't want to do it twice in as many years (usually only within 2 decades or more if you can stretch it)!
These things can therefore take significant time….(DOCSIS3.1) OFDM is still probably a a couple of years away yet from practical commercial quantities at least?
I also suspect VM will want to leapfrog from current 8x4 DOCSIS tuner to 24x8 channels and by-pass Puma6 and Broadcom equivalents before trialling a SuperHub 4 version. Interesting times…..

Re: Uddingston ML5 2 Upstream Channels
Just had a look at http://keepup.virginmedia.com/speedupgrade for the 152Mb upgrade.
And it looks like we will get the upgrade in 2015
-----------------
We’re upgrading the network in your area and your speed boost will be ready between August 2014 and January 2015. You don’t need to do a thing and we’ll contact you as soon as it’s ready.

Re: Uddingston ML5 2 Upstream Channels
This is what it say on the first page about the upgrade.
"Right now you have our up to 120Mb broadband. That's really fast, but between August and January 2014 you'll be able to supercharge your speed to up to 152Mb broadband at no extra monthly cost. We'll email you when it's ready."
On the page you linked its - "We’re upgrading the network in your area and your speed boost will be ready between August 2014 and January 2015"
Nice to see Uddingston late as always....

Uddingston
It's just very frustrating that we are always last to get upgrades.
And are you on 64QAM yet. ?

Re: Uddingston ML5 2 Upstream Channels
no no, you must be mistaken. You need to read the latest news article on the main page titled "152MB is coming soon, Tweets Virgin Media"

Re: Uddingston ML5 2 Upstream Channels
They need to stop boosting broadband speeds and spend the money on the infrastructure. Uddingston falling apart

This phone is 7 years old. It is 100 times as bad now
