RIS is a widely used public route collector project that provides a better view of Internet routing. One thing that makes RIS unique is that it inserts observable patterns of activity into BGP through a process called beaconing. We take a look at RIS beacons and ask how to make space for more.

About the author
Based in Amsterdam, NL
I'm a system architect/research coordinator at the RIPE NCC, where I work in the science group. I'm a chemist by training, but have been working since 1998 on Internet related things, as a sysadmin, security consultant, web developer and researcher. I am interested in technology changes (like IPv6 deployment), Internet measurement, data analysis, data visualisation, sustainability and security. I'd like to bring research and operations closer together, ie. do research that is operationally relevant. When I'm not working I like to make music (electric guitar, bass and drums), do sports (swimming, (inline) skating, bouldering, soccer), and try to be a good parent.

On 2 June 2023, there was a disruption in Internet interdomain routing. We got notified of recurring resets of some routers that take care of routing between networks, due to malformed BGP packets with BGP attribute 28. Here we take a first look at the event through RIS and offer some initial ideas…
In our earlier analysis of Ukraine back in March 2022, we looked at factors that contributed to the resilience of the country's Internet since the outbreak of the war. A little over a year on, we draw on data from RIPE Atlas and RIPE RIS to investigate what has changed.
Speculation about Russia disconnecting or being disconnected from the wider Internet abounds. In this article, we look at the connectivity of the Russian Internet to the wider Internet and how this evolved around the Russian invasion into Ukraine and sanctions related around that.
We are looking closely at what RIPE Atlas and RIPE RIS have to tell us about the state of the Ukrainian Internet. Initial observations indicate that Internet infrastructure in the country is continuing to function as the conflict unfolds.
We created a data aggregate we call 'minRTT' that gives the minimum latency into each ASN (and IXP!) from RIPE Atlas for a given day. This allows us to visualise network deployments and can help with insights into structural latency problems for a network. We build a few visualisations on top of th…
On 23 March 2021, LINX London experienced an outage. As this is one of the very large Internet Exchange Points, this is an interesting case to study in more depth in order to see what we can learn about Internet robustness.
In this post we introduce a wiki to document RIPE Atlas measurements better. We use the measurements we created to track RPKI Repository Performance to show how this is useful.
From 19-20 September, network operators, local IXPs, peering coordinators, Internet researchers and government officials will meet at CAPIF 2 to build a more diverse interconnection environment in Central Asia, Iran, and beyond. To prepare, we’ve been examining changes in local interconnection and …
In this article, Mohamed presents his Google Summer of Code project that correlates and aggregates alarm data to detect real-world Internet outages. His project integrates data from IHR, GRIP, and IODA, visualising BGP hijacking, delays, and outages for improved real-time monitoring.
In November 2021, Internet users from Mexico lost access to whatsapp.net and facebook.com. By the time the event was reported, the underlying problem had already gone unnoticed for quite some time. Here, we present key takeaways from our analysis of the event - carried out with RIPE Atlas - and we …
This article presents a set of open-source tools - “reusable visualisations” - that extend the AS hegemony visualisations provided by the Internet Health Report. Users can directly use the online tools or embed the IHR data on their own posts, webpages, or Observable HQ notebooks.
The events season has started! This article is an invitation to people from across many communities, whatever your role or level of experience, to come and participate in workshops, conferences, camps, lectures, festivals, and more.
In 2021, reports emerged that hosts in Mexico were unable to reach whatsapp.net. It was determined that middleboxes were to blame, intercepting the queries to the root instance hosted in China and sending a bogus reply. This article investigates the prevalence of middleboxes using RIPE Atlas probes.
Following the Facebook outage that took place on 4 October, we saw people looking to BGPlay to get a better view of what went on. Here's a look at what the RIPEstat visualisation has to show us about the event in question.
