Manually deleted A record for conpany's only PDC

My boss was troubleshooting an internal dns issue while I am on annual leave and long story short deleted the a record of the PDC from dns. I asked him if he made any changes prior or after the initial incident was reported to our helpdesk and he advised this was the only one. I told him to undo the deletion so the record was manually re-created.
Should I be worried for any dns horrors with dns resolution, end users etc.
Kind regards.
Ps: We take backups of the system state
