Location: Amsterdam, NL

I'm a system architect 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 visualization and security. When I'm not working I like to play electric guitar and run in circles, while listening to music.

A RIPE Atlas View of Internet Meddling in Turkey

Emile Aben — Mar 31, 2014 10:40 AM

A RIPE Atlas View of Internet Meddling in Turkey In RIPE Atlas we see latencies to Google's 8.8.8.8 DNS resolver service drop in Turkey. We expect this is due to hijacking of the 8.8.8.8 service. Our measurements show a timeline of these events. Note that even when the Twitter ban had been lifted, RIPE Atlas still saw fake 8.8.8.8 DNS service active in Turkey. In the evening of 7 April the situation returned to normal.

Typhoon Haiyan - What we see in RIPEstat and RIPE Atlas

Emile Aben — Nov 08, 2013 03:45 PM

As one of the strongest typhoons on record, Haiyan is feared to have a devastating effect on the Philippines. We looked for evidence of its effects on the country's core Internet infrastructure. At first glance, the typhoon's impact on core Internet infrastructure appears to be modest. This is in stark contrast with the expected humanitarian situation in the affected area.

RIPE Atlas - Packet Size Matters

Emile Aben — Oct 02, 2013 04:30 PM

RIPE Atlas - Packet Size Matters This new RIPE Labs article talks about trying to send large packets over the Internet. Above a certain size, these packets will have to be fragmented, which is known to cause problems. In both IPv4 and IPv6, we see approximately 10% of RIPE Atlas probes that are unsuccessful in pings with fragmented packets, while they don't encounter problems with smaller unfragmented packets.
