Van Jacobson on Codel at IETF 84. Lots of good insight to congestion or the lack thereof on the Internet.

Latency at my local Starbucks
Below is a snapshot of the latency at my local Starbucks taken using my Ping-exp tool. Notice the cyclical latency spikes. In this test the “Low” traffic had the high throughput TOS bit set, the “Default” traffic set no TOS bits and the “High” traffic set the low delay TOS bit.

Sagrada Família
I was recently in Barcelona and took the opportunity to see Sagrada Família.
Wow, I’ve been in a lot of churches but this one completely blew me away. It feels like a building from a Sci-Fi movie. Construction started in 1882 and isn’t expected to be complete until 2026.
IPv6 deployment day is here
A few minutes ago major Internet companies enabled IPv6 permanently. Happy IPv6 day!
