The grace period for expired .ae domains lasts for approximately 30 calendar days. During this period, the domain displays the status:
serverHold (Expired)
serverUpdateProhibited (Expired)
Following the 30 days, an additional domain status is added:
serverRenewProhibited (Expired)
At this point, the domain is scheduled to be purged within 1-2 calendar days. The exact drop date and time are unknown. Drops are processed from morning till noon (UAE time).
You may attempt to register the domain after it drops, or you may request Domain Assistance to evaluate your options.
