Just wondering what the "normal" latency should be with Snap's 100/50 plan. Scenario is this:

1. When I had Snap installed (in Christchurch) I was getting between 0ms and 5ms ping on Speedtest.net.

2. Snap/Enable/Chorus???? then had their meltdown of UFB a couple of weeks ago, which resulted in very slow UFB speeds, which Snap fixed by a call to their call-centre, and geo-location through Speedtest.net and Google was showing me in (a) Dunedin and then (b) Wellington with Pings of 15 to 20ms.

3. Geo-location is now back showing me as in Christchurch and although the speeds are fine (94/48 on Speedtest.net) the ping to Snap's Christchurch server is still high and recording between 13ms and 20ms.

Nothing in my set-up has changed since UFB was initially installed.

Given I'm with Snap on Enable's fibre network and less than 5km from Snap's server I would have expected far lower ping times - am I right?

Hello... Our robot found some keywords in your post, so here is an automated reply with some important things to note regarding broadband speeds.

If you are posting regarding DSL speeds please check that

- you have reset your modem and router

- your PC (or other PCs in your LAN) is not downloading large files when you are testing

- you are not being throttled by your ISP due to going over the monthly cap

- your tests are always done on an ethernet connection to the router - do not use wireless for testing

- you read this topic and follow the instructions there.

Make sure you provide information for other users to help you. If you have not already done it, please EDIT your post and add this now:

- Your ISP and plan

- Type of connection (ADSL, ADSL2, VDSL)

- Your modem DSL stats (do not worry about posting Speedtest, we need sync rate, attenuation and noise margin)

- Your general location (or street)

- If you are rural or urban

- If you know your connection is to an exchange, cabinet or conklin

- If your connection is to a ULL or wholesale service

- If you have done an isolation test as per the link above

Most of the problems with speed are likely to be related to internal wiring issues. Read this discussion to find out more about this. Your ISP is not intentionally slowing you down today (unless you are on a managed plan). Also if this is the school holidays it's likely you will notice slower than usual speed due to more users online.

A master splitter is required for VDSL2 and in most cases will improve speeds on DSL connections. Regular disconnections can be a monitored alarm or a set top box trying to connect. If there's an alarm connected to your line even if you don't have an alarm contract it may still try to connect so it's worth checking.

I recommend you read these two blog posts:

- Is your premises phone wiring impacting your broadband performance? (very technical)

- Are you receiving a substandard ULL ADSL2+ connection from your ISP?

I am the Geekzone Robot and I am here to help. I am from the Internet. I do not interact. Do not expect other replies from me.

Hi Otagolad

Forget about what speedtest.net shows for your location, This is not a Snap issue and 0ms is false it's not possible

Do you actually have a issue with your connection?

Speedtest.net is a guide line only do your own trace routes and ping tests

Hi John,

Thanks for the reply, however the geo-location issue was a known issue acknowledged by Snap and any increased latency is a concern to me.

I know that 0ms is likely a false reading, however in my professional dealings with Enable and Snap network engineers (not through their call centre's but through my work dealings with them) they have previously said that it should be around 5ms. I have done my own trace routes and they match up with Speedtest.net as showing between 15ms and 20ms, which is what my vdsl/adsl2 latency was prior to going to UFB.

you should forget about what speedtest says, do some manual tracerts and paste them here so people can compare

you could check www.snap.net.nz, www.trademe.co.nz and www.google.com for example.

I have access to a SNAP UFB connection from here.

If speedtest.net shows you sitting on the moon this has 0 reflection on the performance of your connection

To Snap's speedtest server I get 3ms now even though I have a direct connection to their network in the same DC.

However I see there is a new speedtest server in North Canterbury that gives me 58ms, so I wonder which your ended up with?

Yes johnr is quite right, location databases are really just best guess's for example most of Snap's customers will show as Christchurch as that is where our main IP Subnets are registered at APNIC, sites like Speedtest have no way at all of knowing your exact location - unless they had some sort of backend hook into our network, which they don't. The location listed in Speedtest and other Geo-site lookup's have absolutely no effect at all on your physical network.

Can you do a ping test from a command prompt to 202.37.101.1 (our anycast DNS) which for most locations in NZ will return a server which is in the closest major centre.

Thanks,
Ralph

Curious how this works - do you simply advertise single DNS host address into BGP with regional metrics?
Is this the same approach for Google's 50+ 8.8.8.8 hosts around the world?

Cheers!

^ correct - it's usually done with a bit of BGP tweaking.

also, it's called anycast, not unicast :p

Oh that is so very clever.

And presumably a separate management channel for monitoring and change.

Aside from the obvious SP and customer benefits, the anycast method makes diagnosing dns issues somewhat challening. Case in point is the new chromecast stick, which appears to be hard coded with 8.8.8.8 which routes across to sydney and inherits the corresponding regional play store entitlements.

Thanks for the quick response and information.

Thanks Ralph - as mentioned, I did also do trace tests and they returned the same sort of results as speedtest.net. I'll run them again tonight and post once I get home from work.

Any idea what the latency should normally look like on your UFB product?
