No broadband for 5 days

[#1]

Briefly... I've been having trouble with my broadband as follows:
- broadband stopped working Monday afternoon, have had only a few patches of very slow and very short-lasting service since (and nothing at all for the last couple of days).
- I raised a fault with PN first thing Tuesday morning and they have done tests and not identified the fault.  They plan to send an 'engineer' next week so I have cancelled work for a day.
- last night I found out that my neighbour has also had no broadband and phone service on Monday afternoon (through another supplier).
I know that my exchange was due to be upgraded to 21CN this week so thought this may be the cause; PN have said my fault is unrelated.  I'm getting increasingly frustrated; as my phone and broadband are both through PN there is no-one else I can call to investigate the issue.  
Has anyone undergone switchover to 21CN, and has their service been suspended during the week it took place?  
TIA

Mine happened overnight with probably minutes of down time.
See what the engineer finds, he may not even visit you.

Thanks for the info.
If I'm going to cancel work for that day, he'd better visit!

Day 5 and nothing has happened. PN presumably do not work weekends so I am resigned now to 8 days with no service.

This morning I had a brief moment of snail's pace internet!  Can anyone help?  Do my router stats look 'normal', i.e. good service?  I was getting typically 2.5Mbps up until my problem began last week.  My router stats are as follows:

Hi tc9604,
Your speed profile has been matched to your IP profile as it had been reduced following the disconnections you have had on your line. Hopefully you will see an improvement.
If not then please respond to your fault ticket #58974490 as they are looking at sending an engineer if no joy with this.

Chris,
Thanks for taking the time to help me - on a bank holiday too.
Speed has now returned to what I had prior to my original problem, however as your colleague mentions on my support ticket the connection is still unstable.  Hopefully it will remain usable until the booked engineer visit.
Tom.
