Three Case Studies on the Egyptian Disconnection
by Mirjam Kuehne 15 Feb '11

15 Feb '11

[apologies for duplicates] Dear colleagues, Claudio Squarcella from Roma Tre University presents three analyses related to the recent events in Egypt, proving interesting behavior in relation to the observed disconnection. He used tools like BGPlay and iBGPlay, developed for the visualisation of BGP dynamics. See his findings on RIPE Labs: http://labs.ripe.net/Members/csquarce/three-case-studies-egyptian-disconnec… Kind Regards, Mirjam Kuehne RIPE NCC

Another view of Egypt falling off the net
by John S. Quarterman 03 Feb '11

03 Feb '11

This view shows paths to six selected nodes inside Egypt, before and during the disconnection: https://www.internetperils.com/perilwatch/20110127.php The timing matches what RIPE saw, and the order matches what Renesys saw. This view is not based on BGP routes; it is derived from regular probes (every 15 minutes) showing hops along the way, and thus shows detail of paths from several cameras outside Egypt to the selected destinations. None of those destinations have reappeared yet. -jsq

Visualizing the Egyptian disconnection
by Richard L. Barnes 31 Jan '11

31 Jan '11

Hey all, Looking to find some more different ways of looking at the current events in Egypt, I thought the routing graphs that the RIPE REX tool produces could be instructive. I've collated the relevant graphs with some notes on what they show in a brief RIPE Labs article: <https://labs.ripe.net/Members/rbarnes/visualizing-the-egyptian-disconnection> Best, --Richard

Comments on RIPEstat
by Richard L. Barnes 25 Jan '11

25 Jan '11

Hey all, As Mirjam announced a few days ago, RIPE NCC debuted their RIPEstat toolbox this morning: <http://stat.ripe.net/> RIPEstat is naturally in a very early state of development, and community feedback is going to be critical for figuring out how it matures, what new features get added, etc. So I thought I would start a thread where people could post any comments they have on the RIPEstat beta. To start, here are my comments: -- Overall, I think the tool is pretty well designed. The interface is very simple, and the results clearly presented. I like that different types of results are displayed in content-appropriate formats (table vs. pie-chart vs. bar-graph). -- The purely text-based interface might be -- I would appreciate it if the sources of metrics could be more clearly identified. For example, it's a little hard to interpret BGP data if you don't know where it's being collected. The "methodology" links on REX did a good job of explaining this sort of thing, so maybe they could be ported over to the new tool? -- In a similar vein, I notice that the time span for things like the stability graphs is fixed. Would be nice to have it adjustable, like in REX. -- It would be really cool if I could download the underlying data whenever there's a chart presented. Seems like that these little micro-data-sets could be cached along with the rest of the results. What does everyone else think? Best, --Richard
