    • Looking at the SonicWall AppFlow monitor, I have significant packet loss (>50%) only when AWS S3 traffic originates from local IP 192.168.168.143. Using ARP I should be able to get the MAC address and then determine the device.
    • arp 192.168.168.143 gives the MAC address. Completing a vendor lookup for this MAC address shows that the vendor is Apple. Remember to try switching networks next time this happens. It turned out to be an autobackup of photos on Mom’s iPad Air to S3.
  • Working with d3, put up a new project page at colin.im/d3experiments/.
  • Highlight code inline via Redcarpet by surrounding the code with ```.
