After an analysis of usage patterns in measurement creation, we have rolled out a couple of changes to the defaults in the measurement form (https://atlas.ripe.net/measurements/form/):

- Under timing, the default is now one-off (instead of periodic as before)

- Default probe selection is now 50 random, worldwide probes (instead of 10 as before)

We hope you find these useful. Please let us know if you encounter any issues.
