I apologize for the incident. We are investigating the issue and will let you know what caused it and what our plans are for preventing this in the future.
Apparently there is a lot more to be done. We are encountering big problems at the moment. Plumsail takes ages to load, then /license call returns 522. Our employees and services are affected again!!
I apologize for the recent service interruption. Our technical team has taken measures to prevent similar situations in the future.
The outage was caused by an outage in the Azure Virtual Machines service. We are improving disaster recovery plan and monitoring systems for similar cases.
Thank you all for reporting and sharing in the community! That is very helpful!
