RIPE Atlas Probes
Interesting! We discussed similar ideas in $prevjob, good to see one hitting production globally.
RIPE Atlas probes form the backbone of the RIPE Atlas infrastructure. Volunteers all over the world host these small hardware devices that actively measure Internet connectivity through ping, traceroute, DNS, SSL/TLS, NTP and HTTP measurements. This data is collected and aggregated by the RIPE NCC, which makes the data publicly available. Network operators, engineers, researchers and even home users have used this data for a wide range of purposes, from investigating network outages to DNS anycasting to testing IPv6 connectivity.

Anyone can apply to host a RIPE Atlas probe. If your application is successful (based on your location), we will ship you a probe free of charge. Hosts simply need to plug their probe into their home (or other) network.

Probes are USB-powered and are connected to an Ethernet port on the host’s router or switch. They then automatically and continuously perform active measurements about the Internet’s connectivity, and this data is sent to the RIPE NCC, where it is aggregated and made publicly available. We also use this data to create several Internet maps and data visualisations. [....]

The hardware of the first and second generation probes is a Lantronix XPort Pro module with custom powering and housing built around it. The third generation probe is a modified TP-Link wireless router (model TL-MR 3020) with a small USB thumb drive in it, but this probe does not support WiFi.

About to leave UPC due to (lack of) port forwarding - Boards.ie
Virgin Media/UPC seem to have silently deployed an IPv6 "carrier-grade NAT" setup called "DS-Lite" -- ie. all customers now get just a routable IPv6 address, and share a small pool of IPv4 NATs. This breaks a multitude of useful services, including UDP IPSec VPNs it seems

Apple now biases towards IPv6 with a 25ms delay on connections
Interestingly, they claim that IPv6 tends to be more reliable and has lower latency now:
Based on our testing, this makes our Happy Eyeballs implementation go from roughly 50/50 IPv4/IPv6 in iOS 8 and Yosemite to ~99% IPv6 in iOS 9 and El Capitan betas. While our previous implementation from four years ago was designed to select the connection with lowest latency no matter what, we agree that the Internet has changed since then and reports indicate that biasing towards IPv6 is now beneficial for our customers: IPv6 is now mainstream instead of being an exception, there are less broken IPv6 tunnels, IPv4 carrier-grade NATs are increasing in numbers, and throughput may even be better on average over IPv6.
