Interpreting WAN quality RRD graph

Here's a non-peak speedtest:
Pings still go up during a download but don't get packet loss, the connection remains responsive for other tasks:

Oh my… You need to change your ISP ASAP. In fact, yesterday was too late...
-
I agree - If your ISP were any slower, it would be Morse Code.
You might even consider switching to carrier pigeon over that service.
Latency is similar. -
We're in a region that has no likelihood of improved fixed line service (the current service is meant to provide >1mbps speed, so most of the time it's better than we can expect). Changing ISP wouldn't achieve anything on the same exchange, and my ISPs bandwidth is generally considered one of the best in terms of consistency https://www.truenet.co.nz/articles/june-2013-broadband-report (Telecom). At some point in the future there'll be a greater than >5mbps wireless offering http://www.vodafone.co.nz/about/rural-broadband-initiative/
-
I wonder what latency is like on the BGAN I-4 Asia-Pacific? Can it be worse?

Round trip for satellites on geostationary orbit is something around 540 ms.

Clicking that link gave me some idea of what he is dealing with…
I clicked it and went and made a pot of coffee and a snack while the page loaded ;D

http://www.vodafone.co.nz/about/rural-broadband-initiative/Some parts of the page still not loaded after 2 minutes here… Edit: Wow, the "tower" image loaded just under 3 minutes...
P.S. Reading the page, I seriously don't think they did get it. The issue is absolutely not bandwidth. With similar latency, speed does not matter.

Their main server is running off this modem I think:

(I used to use this sort of rig for long haul encrypted digital comms. Just incase end of the world gear in my past jobs)

I think Squid and some sort of dynamic content caching system would be the most important thing for someone on a connection like this to have. I really do wish that for things like youtube, hulu, pandora and the whole plethora of semi-questionable content sites out there that pfsense had some sort of out of the box solution to cache them.

Impressive. I think they'd better get out of business soon.
-
Beginnings are always an awkward place. I'm sure they will improve.
I think they should consider static high altitude "Blimp" like satellites for bandwidth.
It faster than towers or satellites and cheaper. Deploy overnight. Can carry enough payload for their entire country on a couple.
Its a no-brainer and yet - it rarely happens… -
I wonder… who's the guy who happens to be in Nepal? Jim? Maybe he could compare that. Maybe moving to Nepal you'd be better off than at NZ, with a nice uncluttered view of Sagarmāthā as a bonus. 8) ;D
-
There are no good bars near an uncluttered view of Sagarmāthā. (and the internet sucks)
I prefer clutter. -
Interesting to hear of how slow grabbing stuff from this part of the world is. Does anyone with the inclination want to try a speed test from either http://speedtest.telecom.co.nz/ or http://www.vodafone.co.nz/broadband/speedtest/ and see how it compares with your expectations?
-
On a sort of related note, you can check average speed for NZ or elsewhere at: http://www.akamai.com/stateoftheinternet/index.html#nui

I put an Alix pfSense in Mugu, Nepal on 192Kbps a few weeks ago. Their ping times to any real internet targets range from 900-1200ms, with some up to 3000ms. Packet loss (as reported on the dashboard, or on a typical ping for a few minutes) is nearly always 10-20%. The town telephone exchange is completely on a satellite link (no microwave towers on mountains yet) and is overloaded. They put in ADSL but they don't have enough satellite bandwidth at peak (or ordinary) times, so calls drop out, internet is slow…
But I have never seen 16000ms! I am rather surprised that a router anywhere would have a packet buffer that would hang on to packets for that long in a queue and finally transmit them on a slow link. In my case in Mugu, once the software has waited 5000ms for a reply it can give up - the packet has been dropped/lost somewhere in the sending and replying.
Good luck getting all those sheep online :) -

WiMax connection:
vs.
VDSL with two IPTV STBs (which causes the sucky ping)
vs.

Yeah, I find it frustrating that a lot of educational resources which would be of benefit in our local schools (which have the same poor bandwidth as us) are posted to Youtube. Which, firstly, seems to be a waste of bandwidth in terms of efficiency of imparting information - me, I prefer static text and diagrams, but most posters don't go to the trouble to make the content of their videos accessible by other means. Secondly, the reality is that they're on there and teachers expect that resource to be available but Youtube and their ilk aren't cache friendly. So then you have to decide whether to spend quite a bit on http://cachevideos.com/ to be able to utilise it easily.

No Java thanks. I'm trying to cut back.
Too much Java makes me jittery.
Yeah - that speed test sucks.
