iPlane traceroute Dataset

Harsha V. Madhyastha — Sep 2010
Contributors: ethankb
This dataset contains traceroutes from PlanetLab nodes and traceroute servers that are done as part of the iPlane project at the University of Washington. This data starts 2006-06-23 and is updated daily. The data hosted on the Data Repository is a copy of the original data that is hosted at the University of Washington, but the historical logs are remastered so they contain only a single tarball per day. Additional data gathered by iPlane such as link latency and loss measurements as well as processed versions of the traceroutes are available at

    I have a valid account . but whenever I try to download the data, it just shows the login screen over and over again although I could log in with the same password, I do not seem to be able to download the traceroute data set. This is kind of urgent, please help me out.

Hi there,
I'm trying to access the iplane dataset but the download link doesn't seem to work. Is there any alternative way to get the iplane data?
Thank you!

Vasileios, in order to download the data sets from RIPE Labs, you need to create an account and agree to the terms and conditions (as described above under "Access Requirements"). Please let us know if you still have problems downloading the data set then.

Hi, Is there a way to download multiple days dataset without having to do them individually? Also do you have any API's which will permit me to download the datasets using wget?
Emile Aben says:

Hi Meenakshi, I think you'll have to download the files individually. I think, if your RIPE Access account doesn't have 2 factor authentication, you can use wget to download the files with the --user and --password options.

Was using wget --user=****** --password=******[…]/traces_2016_08_15.tar.gz downloads ~58kb tar file whereas the file is 836M. Am I doing something wrong?
Mirjam Kühne says:

Dear Sagnik, it is not possible to use wget with username and password. You need to log in to RIPE NCC Access which will set a cookie, then save the cookie in a file and tell wget to use it. I hope this helpw.

  I've downloaded the compressed file, e.g. traces_2015_7_30.tar.gz.
  After depressed the file, there is a set of archives in this file,
  Through other measurement, I find this file should be a JSON file.
  But now the file is consist of hexadecimal numbers, just like: d17c bcf6.
  So now I don't know how to decode this hexadecimal content into JSON format, looking for help.
  Thanks a lot.

  I want to know how to decode the download file into JSON file.
  There is an exception "UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe8 in position 8: invalid continuation byte" when I read the file using file.readlin() in Python.
  So can you please help me? Thanks a lot.

Hi Zixin,

the iPlane data is in a format defined by the iplane project. I remember that there was a tool on the iPlane website to decode the data, but i didn't find it anymore, i suggest to contact the iPlane team for access to this tool. On github there is a tool that might also be able to read these files, which i haven't tried myself but it looks promising: .

    I have created ncc acount and click dataset access in my profile, but when I click the download link to
get to iplane dataset, it keeps bringing me back to dataset homepage, anything missing here?

Hi Dali,

There was an issue with an intermediate system granting access to the dataset; this issue has been fixed, and we believe it is now working as intended again.

Please let us know if you still experience any problems.

Hello, I tried to download this dataset, but the webpage keeps redirecting to
Could you please email me this dataset and NLANR AMP Data. Thanks!

Dear Chenglei,

The full iplane traceroute dataset is 5.5TB; sending this over e-mail is not feasible. However, the service should work but doesn't right now. We'll investigate and fix ASAP.

Apologies for the inconvenience.

Dear Chenglei,

The problem has been idenfitied and resolved - service has been restored. You can now log in and download the data sets again.

Thank you for your patience.

I need to use iPlane data set to measure the latency between different ASes on the Internet. Can you please let me know how can I download it? I have created my account but then the download link is not working, it is redirecting the same page again.

Dear Shahrooz, you need to click the "Tems and Conditions". Otherwise you won't be able to see the data sets. Please let us know if you have any more questions.
