Not as far as I am aware. Given the difficulty in compromising SSH directly and the chance of getting a different IP each time you connect, blocking port 22 outbound seems like an odd choice. It may be down to something else (administrative interfaces, how the lab environment is configured, VPN issues etc).

They said it’s because so many people are using the default credentials, which leaves them open to easy access.
