You want a static IP.

You try several different modems that are known to work ok (like from friends or relatives).
If you've got copper network then you get the lines checked for rot.
With copper it's also best to be less than 1km from the exchange, less attenuation.

Then there's only really the DSLAM. If it's getting loaded up then you can only switch to a different one. Smaller IPS's use larger telco DSLAM and with some you can actually switch DSLM without switching ISP (like here a small ISP will use Telstra and Optus DSLAM in some areas).


Fibre is different 'cos you don't have to worry about line rot, I'm not sure about line attenuation but I assume it wouldn't be an issue like with copper.
But a DSLAM is what it is. If it's loaded up not much can be done. And sometimes they can develop faults too.
Interesting. I think Virgin Media need to check their exchange outside of my home... A few years ago (2009) they had to come out and fix some wires in the exchange. The pit was flooding with rain water, and given the fact that was almost 5 years ago I bet the same thing has happened again.
