EOL NL had an outage starting from 04.45 to 06.28. The EOL Webservers were unable to connect to SQL. The Exact infra team have mitigated it by deinstalling a Microsoft update on the domain controller which was targeted at hardening security (Kerberos/Netlogon).
The out-of-band solution patch of Microsoft is now installed on all domain controllers and solved the Kerberos management service accounts issue.
