hmm excuses.
TW have a smaller network but lets get things into proportion here. Announcement made, 2 weeks later TW upgraded = 14 days, for sake of argument lets say summer from 21 june to sometime in sept, middle date 1 August = 90 days. So ntl's network is over 5x as big as TW?
Am I talking rubbish? yes
Is this rubbish also?
DHCP upgrades (for speed upgrade?)
Training (5 mins in staff meeting)
Thousands of config files (done in bulk)
Education (for what exactly?)
Billing (so it says 1.5 instead of 1meg service and even if this was wrong it doesnt matter as its free upgrade and what you charged counts, either way its probably just 1 change in a database)
Capacity Calculations (this should have been done before announcement)
Checking if modems work (yes mine works

not sure what you meant by this)
Updating UBR's (its just a config file

)
