Our contact at SNSF confirmed that the power interruption was due to maintenance work by the electrical utility company, and that connection continued to be available throughout the outage via our secondary router.

The router became reachable again, noting that it had been power-cycled.

Tried to call SNSF contacts to check whether this is due to known maintenance work, but couldn't reach anyone.
