Suricata alert ET SCAN NMAP -sA on all googles ip address

Hi everyone, i have notice that all google ip address is scanning services our network and suricata is keep on blocking them. The problem is, when they are block we cannot access google service such as gmail, google drive, and youtube. Is this alright? should i whitelist googles ip address in suricata? by the way the alert is ET SCAN NMAP -sA.
