You raise an interesting point Tim. The last renew date was March (ie. now). However many in my area have been complaining of complete loss of service for mulitple days. Where this has not affected me (slow speeds yes, totally off no), I am hoping this is part of the long coming promised upgrades.
If customers have been affected by total loss of service in your area, as I am unable to check this, it could of been an issue at the local exchange or maintenance work. We can only check this if the customer with the issue gets in touch.
For your own cable there is work scheduled for a re-segmentation to be completed and hopefully you will notice a improvement with the connection.
In regards to your speed upgrade, I can see that this will be ready for you between May and July 2017.
