There was an original incident related to the user search functionality that caused significant downtime for the feature. In order to avoid the re-ocurrence of a similar event with that magnitude actions were put in place, however, the meant significant changes that caused some restrictions to be put in place for some accounts (if you were affected by these restrictions the incident linked above includes an email address you can use to contact Auth0) and also caused some much shorted feature disruptions while the situation is not fully stabilized. If you check status page (which should be your first source of information for situation such as these where the service is disrupted) you’ll see that in the last days (apart from an issue affecting a percentage of request in EU today) thinks have been more stable.
We are still making actions towards resolving the situation completely so I’m not going to claim that instability is over, however, as you might imagine it’s as much as your interest as ours to have a stable situation as soon as possible. Thanks for your patience and comprehension while things get to that point.
