Re: Post Your Fibre Think Broadband Ping Graphs (Not VirginMedia Cable)
 

Pure guesswork but I take it your mate lives at the end of a very long (a few miles) piece of copper from the exchange judging by that base latency (either that or a fault possibly) , probably gets about 1 mbps download speed so dead easy to max his line out and make the TBB graph look pants.

Maybe the more knowledgeable gentry could expand on my suggestion :)

Also, what exchange is your mate connected too, it might be one that's suffering from hi demand.

That is the highest constant minimum latency I have seen. Some kind of adsl connection at the furthest distance any isp would dare to accept the connection?

The 6pm to 4pm looks like heavy usage as its ok the rest of the time, bar the high min latency

I replied not seeing your post as it was on the next page, but I was obviously thinking along the same lines as you :D

Re: Post Your Fibre Think Broadband Ping Graphs (Not VirginMedia Cable)
 

The line would have to be 6000km long to cause that kind of latency.

The latency is nothing to do with line length, it's the interleaving that is the problem.

Re: Post Your Fibre Think Broadband Ping Graphs (Not VirginMedia Cable)
 

++line length = more interleaving required = higher latency

So line length is a factor ;)

Re: Post Your Fibre Think Broadband Ping Graphs (Not VirginMedia Cable)
 

Line length does not require interleaving, interference and noise does.

I've seen more interleaving on a 90m line than a 1900m line.

Re: Post Your Fibre Think Broadband Ping Graphs (Not VirginMedia Cable)
 

Still a strong positive correlation between line length and quality, there may be exceptions but on the whole...

Re: Post Your Fibre Think Broadband Ping Graphs (Not VirginMedia Cable)
 

I agree with you, Craigie. To put it politely, Qasi's peeled the onion back one layer; putting it otherwise, he's nitpicking again!

Re: Post Your Fibre Think Broadband Ping Graphs (Not VirginMedia Cable)
 

I disagree. There is a strong correlation between line length and attenuation, nothing else.

FYI, my Sky phone line developed a fault on Friday resulting in an earth fault external to the property, the phone was dead (but noisy), and the broadband was working OK ish, voice chat on xbox live was poor though as my mates kept saying I was breaking up.

Anyway I reported it too Sky about 5:30 on Friday evening, and by lunchtime Saturday it was fixed. It turned out to be a faulty twisted pair coming from a post some 5 meters away, whilst hear the engineer put fresh connectors on all our streets phone lines and the results are below, a thumbs up for Sky tech support, the BT Openreach engineer was fantastic, polite and professionally (took him 2.5 hours to find and fix the fault).

Nice result considering,

Superb Pabscar! Not only a very fast fix but above and beyond what is expected with all the new connectors for the rest of the street. Quality :tu:

Slightly fluffy blue line with lower base latency to smaller blue line with higher latency without a resync, still fastpath.

Summary: Mystery BT network does stuff

Re: Post Your Fibre Think Broadband Ping Graphs (Not VirginMedia Cable)
 

1 or 2ms increase isn't too bad, does make you wonder what changed though!

Still in the first 24 hours of the new fibre install but its looking as good as I had it at my previous home. Moved out of London so wasn't sure what to expect.

Few bumps was me doing stuff.

Re: Post Your Fibre Think Broadband Ping Graphs (Not VirginMedia Cable)
 

Sweet base latency Qtx

Re: Post Your Fibre Think Broadband Ping Graphs (Not VirginMedia Cable)
 

Think its 1ms higher than at the last place but im not complaining :D

Not sure if I have been lucky or if all their new fibre installs are as good. Stress testing the connection at the moment, just nice to get off the wifi hotspot through my mobile even though it served me well.

Re: Post Your Fibre Think Broadband Ping Graphs (Not VirginMedia Cable)
 

I reconnected a couple of times last night to try to get a different IP and lower things - the big red line while DNS updates.

Then it seems over night there's been 3 different states and 5 changes between these. Odd.

That graph is brilliant Qtx, gonna move to sky I think. Any chance of a tracert to qw.foppa.dk?
