SpeedTestBot: Verify your average broadband speed
After months of intermittent reliability and inconsistent performance from my broadband service I decided to do something about it and collect some data about how it actually performs. Enter SpeedTestBot “Everyone’s friendly broadband tester”.
I have a package from Virgin Media that provides “up to 70 Mbps” - broadband packages are usually advertised as “up to a value” and certainly not a fixed value. How close does it get, on average?
This package price has risen ~£10 in the last year and apparently the speed has increased ~20 Mbps. Am I getting value for money?
I hacked together some code quickly that can be run on a schedule to automatically test your broadband speed via speedtest.net and record and optionally tweet the daily average results. Every 24 hours it can calculate the mean average download, upload speeds and ping latency of your broadband service from your side of the router.
My average broadband speeds over the past 24 hours are download=48.69 Mbit/s upload=3.82 Mbit/s latency=39.3 ms. From SpeedTestBot.— fibostein (@fibostein) March 11, 2016
This is not new. There are instances of other people trying this, for example a Comcast customer in the US.
My experiences may not be representative of others problem because each environment is different so YMMV.
There are obviously a vast range of factors that can affect the performance, here are a few:
Local network issues:
WiFi is too variable, network congestion.
Action: These tests are run on a device with 100 Mbps ethernet connection to the router.
This is a bit of hardware and software built by humans - it suffers bugs and issues the same way as any other bit of tech does.
Action: Not much I can do here. The router is 4 years old - maybe this should be replaced?
The code allows Speedtest to auto select a host to test against, this is variable and so the distance to the host may have an impact.
Action: TODO Select from a list of preferred hosts.
Over-subscription. I am not 100% if this is applicable to a fibre optic service but the speeds do noticably dip in the evenings.
Are all other variances down to broadband provider?
For me the average speed is not that important but the data and the range of results is interesting. Having an average speed of 100 Mbps over 24 hours is useless if it’s 150 Mbps overnight and 50 Mbps during the day when you need it. The number and regularity of outages is also concerning and something I’ve noticed when working from home.
Personally I want value for money from my service; I would rather have a constant but reliable speed and service rather than something that is occasionally fast but not stable. I am looking somewhere else for this now.
Broadband is a right and in today’s world it is a problem when it is not consistently available. Companies that provide an up to service should ensure that 1) the service is available and consistent 2) should at least be capable of reaching the speed advertised rather than this just being a theoretical limit 3) not over-subscribe to the extent everyone suffers.

I think 3pm was either a VirginMedia outage or speedtest.net, up to the reader to form that opinion - this is not an isolated occurance.
After a couple of weeks the mean average is ~40 Mbps download and ~3.9 upload.
Self explanatory, have a look at the README. It’s a bit of bash, python and APIs.
