Outgrowing your IPv4 allocation is one of many very good reasons to get on with deploying IPv6. Here's a use case on the latest steps the RIPE NCC has been taking in the piecemeal process of deploying IPv6 across its services.
The start of 2021 saw RIPE Atlas users encountering delays in data retrieval and an overall drop in the responsiveness of the system. Now that things are back to normal, we thought we’d take a more detailed look at what happened and the steps we’re taking to prevent it from happening again.
The RIPE Routing Information Service (RIS) and RIPE Atlas produce large amounts of data that needs to be processed, stored and made available to the public. We've been using Hadoop for some time now. In this article we look at the design of the infrastructure we currently have in place and describe…

“Hi, when I try to wget Waikato traffic files from these servers the connection gets dropped after a few seconds and I'm left with a piece of the file. WAND describes this behavior would occur on their own servers for ipv4 downloaders. I am using ipv6 and I'm able to download from their servers, so I'm a bit confused why it happens on these servers. Please let me know if you can reproduce this, and if I should provide more information. Many thanks in advance, Eyal”
Hi Eyal, I've tried to reproduce your issue but it seems that I can't: the downloads work fine for me, and I get files of the appropriate size. There could be some on-path problem preventing the download from completing successfully for you; could you try different locations to download from? Alternatively, you could try to do partial downloads using HTTP range requests (see e.g. -C or -r in the curl manpage). As we are unable to reproduce your issue, there's not much that we can do to investigate the problem. If you find anything else, please let us know! Thanks, Paul de Weerd RIPE NCC
“hi, how can i open the downloaded file for RIS data servers in linux? it reports a problem! do i need a large storage ? i have both windows and linux in one pc”
Hi Hasti, As mentioned in the article, the data can be read with libbgpdump. Please see https://bitbucket.org/ripencc/bgpdump/wiki/Home for the latest code.
“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. Cheers!”
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.
“Hello, I tried to download this dataset, but the webpage keeps redirecting to https://labs.ripe.net/datarepository/. Could you please email me this dataset and NLANR AMP Data. Thanks!”

“Hi, 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? Thanks.”
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. Cheers!
