Today, the team behind Laracon US announced on Twitter they are canceling the event due to COVID-19:
We have postponed Laracon US 2020 and are refunding all orders. We have to refund each order individually so that may take a few days. We will be back soon with news on our next steps, including a possible online event.
Both Laracon EU and Laravel Live have canceled as well. As soon as we get information about these events we will be sure and pass them along.
