One signal

The National Energy System Operator says its core systems and operation of the electricity system are unaffected by the Microsoft 365 disruption. It says alternative communication arrangements are in place where needed.

That is a useful distinction amid reports of problems with Outlook and some Teams communications: Neso says the disruption has not affected electricity system operations. The statement appears in New Civil Engineer’s coverage of the outage. For infrastructure operators, resilient fallback communications matter. Less reassuringly, keeping a critical service running while its ordinary tools wobble is not the same as proving every knock-on effect has been ruled out.

Discuss: Should critical infrastructure operators be expected to publish clear assurances during major technology outages, or can that create false confidence before the full impact is known?
