We've identified the issue with our European MQTT infrastructure.
A large number of MQTT connections was opened from a couple dozen IP addresses, exhausting available sockets. We have set different limits on the number of connections per IP address and the number of connections per username. Most normal deployments should not be impacted by this.
We're monitoring the status and will issue updates when necessary.
