These screens build information from multiple sources inc. airlines, ground control, and in some cases airport management. They're typically run off-site at a data center since that provides high resiliency and some data is sourced from outside the airport anyway.
If the airport has a dedicated fiber channel between their data center and airport itself and it was damaged, this could be the result. The question I'd ask is why they have no fallback strategies (e.g. cellular, VPN over a less secure internet channel, etc).
This might be an area where they can explore graceful degradation, meaning that gate information would continue to display (from airport ground control), but some flight times might be missing.
