Clean-up of line
« on: January 02, 2020, 09:34:04 AM »

Here’s the state of my lines :
Live sync rates:
  #1: down 3132 kbps, up 515 kbps
  #2: down 2968 kbps, up 519 kbps
  #3: down 3187 kbps, up 416 kbps
  #4: down 3158 kbps, up 531 kbps

Speed tests done with speedtest2.aa.net.uk give :
    IPv6 10.86 Mbps down; 1.58 Mbps up
    IPv4 10.82 Mbps down; 1.58 Mbps up (all the above need correcting for the overhead of TCP and IP, I would think, which would give higher numbers) : (sum = 12445) * (0.884434 protocol efficiency) = 11007 kbps, needs reducing a bit for headers so 10.86 is good!)

Ookla speed tester app, via test server “Cloud ConnX Eastbourne”:
    10.6 Mbps downstream, 1.52 Mbps upstream

All those lines being so fast downstream, 300k downstream sync more than usual, and holding up stable for so long, 12 days to present, is very unusual. So what’s going on? Well this is all after the month of hell and the many subsequent repairs, going on for weeks. Openreach has traffic lights set up in the centre of Broadford on the main road too; don’t know what that’s about, unlikely to be related. I’m thinking all the repairs must have ‘cleaned the lines up’ somehow; fixing bad joints maybe. Is this a reasonable guess?

I thought that there had been a serious zap of some of the E-side cables exiting NSBFD in that storm incident?

Yes, that will be the case. If you remember there was an Openreach team, working down a hole, near the Harapul fank (hope I've used the correct spelling) that made a significant improvement to your four circuits.

It’s really quite a big deal, nearly 8% in downstream sync, nothing in upstream, although the worst offender the duff line 3 u/s is perhaps less awful now.

I agree about a ‘serious zap’. I remember mention of ‘soot’.
