The internet felt a bit quicker than normal today, so did a quick speedtest:



That was over wifi, and previously even over a wired connection was never getting over 29/9.5:



Has there been a recent change to over-provision the 30/10 plan?

I'm on Spark UFB in Auckland.

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?

You're honestly expecting us to believe you can "feel a difference" between 28.5Mb/s and 31.6Mb/s?

I'm Confused.

That's easy enough to tell in some cars, others not so. 29mbps vs 31mbps is not really discernable without a specific measurement or test imo :P

In my experience, OOKLA speed tests are approximate and never the same twice, even if taken only seconds apart.
Which is what you'd expect on a system with continuously varying traffic.

Differentiating 95 to 98? In some cars it certainly is. In most production cars it's not. But we're getting off-topic. My upstream bandwidth just dropped by 42bps so I better slow down...

You're going way off topic, but you're saying a car that is tuned for 100 octane (Pretty much any JDM performance car) won't pull back timing when you're running a lower octane fuel? I guess 91 makes no difference either then and the knocking notice you can quite clearly hear when you run a high CR car is not an issue?

You've probably been moved from the Bitstream 2 to the Bitstream 2a profile from Chorus (assuming you're on Chorus). And since you're with Spark it probably happened when you moved to a Voice over Fibre line??

The Layer 2 speeds of the 30/10 plan is actually 33/11. So that should give you a Layer 3 speed of 30/10.

Since there were a number of complaints about why customers on 30/10 couldn't get an actual 30/10 speed test. Then the whole Layer 2 vs Layer 3 conversation comes in an 99.99% of customers eyes glaze over.

If you order 30/10 you get 33/11 Layer 2
100/20 you get 110/22
100/100 you get 110/115
200/20 you get 217/22
200/200 you  get 217/230

It's a long story about why the upstream is higher... But that is what it is.

The 100/50 plan is a Bitstream 2 plan, which isn't actively offered by many ISPs since it's more expensive than the BS2a plan. Hence why that speed seemed to disappear from most ISPs when the 100/20 came out.

I'm sure there is a document on CFH talking all about Bitstream 2 vs Bitstream 2a plans somewhere.

I am speaking about joe average modern production fuel injected road cars not something that needs 100 octane

I believe this came about thanks to James of InspireNET who lambasted some chorus management about creating "right performing" UFB plans that werent so picky about PPPoE and throttling overheads. I didnt understand what he was on about at the time but it seems to have made a difference as I have noticed since ordering chorus ufb tails that they perform slightly better than spec. Though that could also be because we dont use PPPoE

It may be perhaps that you have been changed to a right performing profile.

No over-clocking that we can see in Chorus connections.  We do see it in Enable though, with 3 out of 10 Snap connections that I can find which are running about 31Mb/s.

Here is our plot of Spark 30/10 - Three of which are Enable connections - BTW there are 9 lines in the chart representing 9 panelists, most are under the 28Mb/s top colour.

Wrong John... it's not always possible but it IS possible in some cases. On my lotus replica for example, the tune is specifically for 98, and if I put 95 in it, it's noticably different. That's not a production vehicle example for sure - but it's an example where in at least one case, I know it's different.

In some turbo vehicles as well, there's a measurable difference in power between 95 and 98.

For most Normally aspirated, non sports cars, it will be difficult or impossible to tell the difference.

and 28.5 to 31.x... hahahahaha. There not a chance that the bandwidth difference will be able to be "felt"... Now... There are other changes which could be felt but I don't think they have been done.

Cheers -N

It honestly did feel quicker embarassed

I agreed to move over to a Voice over Fibre plan last week but the tech hasn't been round yet for the wiring change.  I know there is over-provisioning on the higher speed plans but this is the first time I've seen it on my 30/10 plan.

Probably a tail wind... Give it a few days and the prevailing westerly will be back, and your broadband will return to Normal.
