Update 05/03/22: This issue is now resolved. It was caused by a combination of two factors: misconfiguration of the DHCP behavior for out-of-band interfaces, and a failure causing an out of band switch to power off.
All affected nodes should be reservable again. If you have an instance that has become inaccessable, please get in touch with us via the helpdesk.
