Domain zone is not removed from SSH-manageable name servers when all domain subscriptions (Domain Registration and Plesk Domain) are removed from OBAS.
When a domain is removed from OBAS its zone description is removed from
named.zones on SSH-manageable name servers but the
.zone file stays until name servers are synchronized.
.zone file of a removed domain will be removed from SSH-manageable name servers within 1-2 days by OBAS daily tasks. To speed up deleted domains zones removal from a certain name server, please go
Top > Service Director > Domain Manager > Name Servers, select the name server in question and click Synchronize.
