Around 90 people met in Manchester  at UKNOF51 on Monday and Tuesday 3rd and 4th April 2023. This was our first multi-day event. In 2023 we are running two, two-day UKNOF events instead of three one-day events. There were also around 30 remote participants using Zoom, submitting questions in Mattermost.

This was another hybrid event. Most speakers presented in Manchester with some joining over the Internet. 13 speakers presented on a variety of Internet operations topics. We also programmed plenty of time for people to speak with each other.

We will publish recordings of the talks from UKNOF51, so you can review the details of talks you enjoyed or catch up on a talk you missed.

Please take our survey.

The first day ended with a social event. Pints n’ Packets was sponsored by Smartoptics.
