How Elasticsearch and Kibana Help us Analyse RIPE Atlas Data Logs
How Elasticsearch and Kibana Help us Analyse RIPE Atlas Data Logs
Andreas Strikos — 29 Apr 2016

RIPE Atlas backend applications run on more than 40 servers. Each day these machines can produce thousands of application logs of any kind of severity level. In order to be able to track down serious errors, warnings or even unusual behaviour, we decided some time ago to try Elasticsearch as a logging sink. In this article we will look at the design of such a system and describe how we can easily make sense from an ocean of logs.

Update on RIPE NCC Authoritative DNS Services
Romeo Zwart — 07 Apr 2016

Recently we have seen an increase in the frequency of excessive traffic towards the RIPE NCC DNS infrastructure. Our servers generally absorb peak loads without an impact on our DNS services. However, to be better prepared for extreme traffic floods, we will work with an external party to provide additional DNS service capacity for serving the ripe.net zone.

Improving "Syncupdates" in the RIPE Database
Improving "Syncupdates" in the RIPE Database
Alex Band — 06 Apr 2016

Over the last couple of months we've been putting a lot of focus on improving the usability of the RIPE Database web interface. We started with tightly integrating our Single Sign-On system, RIPE NCC Access, into webupdates. This allows users to seamlessly make changes in all of the different RIPE NCC service interfaces while only requiring a single set of credentials. Then we added better validation, auto-complete, "diffs", integrated abuse-contact creation, updates in a text-area and many more tweaks and improvements to enhance the user experience. The last big part of the RIPE Database web interface that was left untouched is Syncupdates. Until now...

How Pingable are the Pingables?
How Pingable are the Pingables?
Rene Wilhelm — 05 Apr 2016

In February 2011 the RIPE NCC implemented the "pingable:" and "ping-hdl:" attributes in the RIPE Database. These attributes were added to the Routing Policy Specification Language by RFC 5943 to allow networks to advertise IP addresses that are reachable and can be used as a target for diagnostic tests. Five years later we check how the new attributes have been adopted and how reachable the pingable addresses registered in the RIPE Database are when pinged from RIPE Atlas.

RIPE Atlas Update: DNSMON Code Available, LatencyMON Comparisons, New Credit Sharing and More
RIPE Atlas Update: DNSMON Code Available, LatencyMON Comparisons, New Credit Sharing and More
Suzanne Taylor Muzzin — 30 Mar 2016

In the past few months, we've added some new features and functionality to RIPE Atlas, including making the DNSMON code available on GitHub for personal use, displaying IPv4 vs IPv6 comparisons in LatencyMON, new credit sharing options, and new limits on probes per measurement and results per day. Learn more about the latest updates - and don't forget to tell us what you think.

Support for Elliptic Curve Cryptography (ECC) in DNS Resolvers as Seen by RIPE Atlas
Support for Elliptic Curve Cryptography (ECC) in DNS Resolvers as Seen by RIPE Atlas
Maciej Andzinski — 21 Mar 2016

The Elliptic Curve Cryptography (ECC) is becoming increasingly popular in DNSSEC. While it is sometimes considered to be a remedy for the low DNSSEC adoption rate, there is also a lot of controversy around it. One of the main concerns is that DNSSEC-validating resolvers don't always make use of ECC. We used RIPE Atlas to measure the support for ECC in DNS resolvers.
