As far as I can see with what can be checked from this side I I'd not be too concerned as the connection seems to be quite stable but let me know if you've seen any noticeable effects.

In your situation, the errors are identified by the "Uncorrected blocks" number, but the important thing is to see - when your line is performing at its worst - how that count is changing relative to the total number of RX blocks.
In the information displayed above, you are seeing about 5% of blocks with errors in. If it stayed at this rate throughout the day, you'd expect to see some impact, but not too heavy - maybe a loss of 10% of your throughput on speedtesters. However, my experience so far suggests that the overall experience degrades much less gracefully when the error rate gets to around 10%.
Next time you get an evening where the experience has halted (and the errors are rocketing), can you take some snapshots of the RX count and the Uncorrected count?
Another possible tool is the TBB Broadband Quality Meter, which sends regular "pings" to your router, and allows you to monitor the latency & level of packet loss. Take a look on TBB's website - that would give you a graphical representation of when everything grinds to a halt.
I have to say that, to me, this error count looks bad enough that it *ought* to have tripped DLM by now. I'm not sure why it hasn't. My copy of the DLM thresholds suggests that an MTBE of 60 seconds should trigger a DLM slowdown (or addition of interleaving); one error per minute over 8.5 hours would be 510 error. This is *way* over that.

I will download the monitoring tool you suggested as well.

The BQM isn't downloaded as such. It's a server-based setup that sends packets to you, and measures the response. You'll probably need to configure the router so it responds to the pings.

Update: Even with Ping enabled, nothing...a very blank graph :-\....spoke too soon, something is now appearing

The first is when I first got FTTC, and the second is 2 days later, when DLM intervened.
Unfortunately, the fibre modem was locked, so I couldn't get to the actual error stats at the time - and can only see the impact the errors had on the ping packets.

My monitor has started now, so I will let that run through the night and tomorrow and will post what it shows.
My router did restart just now...not sure if that was because I allowed the ping response which made the router reboot?!?...in any event my Rx and Error blocks went back to zero again.

PS: Router now up 35 mins and showing RX Blocks: 1090852, Uncorrected Blocks: 3923
