On Thursday, 27 January, from 8:00 AM to 4:00 PM EST, ARIN will be performing maintenance that will affect its Whois directory service. During this maintenance, users can continue to query ARIN's registration data through the RESTful web service, NICNAME/WHOIS port 43, and our web site (whois.arin.net). The results returned, however, will not reflect any changes being made to ARIN's registration data after the start of the maintenance period. When the maintenance is complete, the Whois-RWS servers will be refreshed with the most recent data, and will resume their normal periodic update schedule. We apologize for any inconvenience and thank you for your patience.
