Just a small remark to clarify some terms for those who might read this topic later. We call "GMS" the self-hosted program that we offer. It is installed on the customer's premises and facilitates Internet ID connection without resorting to any third-party services.
Whereas the ID server in question is our company's server that we maintain. It's the default option for the Internet ID connection in Remote Utilities. We were doing some maintenance and update and it took longer than we initially planned (otherwise we would have notified everyone beforehand, of course). So again, sorry for any inconvenience.
