Oproep aan voip providers

Netneutraliteit is met name belangrijk voor voip providers, omdat sippoort 5060 vaak het eerste slachtoffer is bij poortblokkades is. En dus, neem contact met ons op, de ervaringen van open internet NL zijn openbaar en we praten je graag bij over wat we speciaal op voip gebied ontdekt hebben.

Sommatie naar Online

In de meetresulaten kleurde Online behoorlijk rood en dat was vorig jaar reden om ze een beleefde brief te sturen. Hun mondelinge antwoord was reden voor nog een brief en vandaag 16 maart ging de derde brief op de post, ditmaal van onze advocaat Ot van Daalen.


Hierin vragen we ze vriendelijk de blokkade in hun modems op poort 5060 voor 31 maart 2015 ongedaan te maken.

Drukke correspondentie met providers

Naar aanleiding van de meetresultaten hebben we de afgelopen maanden contact gezocht met Ziggo, KPN, UPC en Online. Voorzichtige eerste conclusie: (bijna) niemand blokkeert expres poorten of toepassingen, maar daarmee is nog niet gezegd dat er niets geblokkeerd wordt.

The story continues...

Slotpresentatie in de Waag

Het einde van het Open Internet project begint dichterbij te komen en op 4 juni 2014 was de slotpresentatie in de Waag Society in Amsterdam.

Thema van de avond was netneutraliteit. Dankzij de Community Grant hadden we ook collega-ISOC bestuursleden uit Polen, Duitsland en Spanje kunnen uitnodigen.

Meetresultaten online

We hebben de meetresultaten online gezet, zodat je per land kan zien hoe de providers het doen in onze tests.

Rood betekent niet per definitie een schending van netneutraliteit, maar wel dat het de moeite is om verder te gaan kijken wat er aan de hand is.

Tweede Community Grant voor Open Internet

Op 25 november 2013 kreeg Open Internet nl een tweede Community Grant. Het doel is ditmaal de meetresultaten online zetten, en een slotpresentatie en een eindrapport te realiseren.

The case of Dutch MVNO Simyo and net neutrality

4th of July 2013: on the Dutch internet news site Webwereld journalist Peter Olsthoorn wrote about the results of the Open Internet tests: MVNO Simyo, a daughter of the Dutch incumbent KPN is obstructing VOIP traffic by blocking UDP port 5060, see (in Dutch) Webwereld.

KPN denied the allegations, and a lot of the reactions to the article were equally incredulous.

They are wrong and we are right of course. Please check our replication of the tests on youtube here .

Open Internet app in Apple appstore

From the 24th of June, the Open Internet app is available in the Apple appstore, and we see a substantial number of downloads already. The search terms are "Open Internet" and the category is "Utilities". Please leave a review after you have taken it for a test drive.

This is how obstructions work

There are quite a few ways in which Internet service providers can interfere with your browsing experience:

- Basic: block the port number. This will block any application that uses this port.

Please continue reading

And this is the way the app works.

Each session starts with the app collecting two kinds of tests from the server: the first kind looks for blocked ports – see the next post – and the second kind investigates whether packets can travel across the network without being tampered with while underway.

Continue reading

This is the way ports are tested.

De app tests ports using UDP and because the app was written in Java, it does so by trying to open sockets:
try{ socket sc = new socket(ip, port);
result = true;} catch (exceptin ex){ result = false;}

At this moment, we are trying for trying three open ports: 5060, 6881 and 23999.

To check your test results, try setting up a UDP session - for instance using the UDP app from the playstore. Enter the IP-adress and the port number you see in the Youtube clip. The results should match the app from the app.

Found an obstruction? Looking for testers!

The new version of the app has not been around for very long, but it immediately started to produce some interesting results on a number of networks.

That is why we need more testers and more tests asap.

To begin with, tests are needed on KPN Mobiel, and Simyo (which by the way uses the KPN network).

At this moment we are not sure whether different subscriptions will encounter different types of shaped networks, and so: the more tests and testers, the better!

Betaversie of the app is on the site

Today, the 22nd of November 2012, marks the start of the Open Internet project, and from this morning, the beta version of the app can be downloaded from the site.

This is what it is capable of:
-for android
-tests for blocked ports
-sends the test results to the central server

And we are working on:
-iOS version
-different screen sizes
more tests

Open.internet.nl wins community Internet Society Community Grant

Open.internet.nl has been selected by the Internet Society for its Community Grant worth 8,900.00 USD. The grant will be used for design, publicity, IT and development.

Competing for a community grant

Twice a year, mother organisation ISOC.ORG awards its community grants to whomever has the best plan to promote an open internet. The prize is 10.000 USD and of course, Open Internet joined the race. Last week the mighty head office sent in its questions about open internets’ application. continue reading

2de release Open Internet App from januari 11 2013

The year 2013 started well for Open Internet, with the release of the open internet app v2.0 on the 11th of January. While v1.0 only tested for blocked ports, this new release has added deep packet inspection. It simulates protocols and checks the results for speed and integrity. Join the test and download the app.

We are moving!

Until now, the server was hosted at Budget Phone Company - many thanks! But of course, a test server is still a test server.

Shortly we will have a brand new server, paid from the community grant, and we will move to the Science Park in Amsterdam. Thanks to the Internet Transparency group - Jeroen van der Ham and Cees de Laat - the computer will be hosted at the University of Amsterdam. Again, many thanks!

Open Internet NL

Open Internet NL investigates whether often used applications such as internet telephony (SIP and Skype), Whatsapp (XMPP), Youtube, Bittorrent
 and Spotify are being blocked or shaped by internet service providers. By promoting the app, the Internet Society hopes to start a public discussion on the the transparancy of Dutch internet providers. Continue

13 privacy policies

This month ISOC chapters from all over the world helped translating the open internet app into as many languages as possible. Take a look at the result our privacy policy in 13 languages.
