Re: [gaia] Heterogeneity in network capacity: growing?

Hi Michael

A good starting point is Ofcom's infrastructure annual report; here is the 2015 one:
http://stakeholders.ofcom.org.uk/binaries/research/infrastructure/2015/downloads/connected_nations2015.pdf

You will find several distribution graphs like the one in Figure 4 that compares the monthly usage to the access speed range for 2014 and 2015.

You could also find the reports from previous years to see how things have changed over time:
http://stakeholders.ofcom.org.uk/market-data-research/market-data/infrastructure/?a=0

For a more global point of view, you could check Akamai's State of the Internet Report:
https://www.stateoftheinternet.com/resources-connectivity-2015-q3-state-of-the-internet-report.html

or play with their visualisations:

Hope this helps
Achilles

First,

Apologies for asking first formulating a question in two ways with contradictory outcomes (yes/no) and then saying "I guess the answer is no" - that was confusing!  :)   I was tired when I wrote it...
so I meant the second question, i.e. my guess was also that heterogeneity *is* growing.

How would you calculate if there was data: I guess what I'm interested in is bandwidth statistics: how often do we see a bottleneck of X bit/s? The Internet-wide distribution of X is what I'm looking for...

Depending on area/market: I'd also be happy to have X for India, X for Europe, X for ... whatever. It's a start!
Ideally citable - some publicly available study I could refer to.

Cheers,
Michael
