Hello IETFers, We are happy to see the excitement from the community for IETF 100 in November! At this point, there are sold out dates at both the Swissotel and Fairmont. The Fairmont has no available room nights on November 9th, 10th and 18th, and the Swissotel fully booked on November 10th, 11th and 17th. We are working to add room nights on these dates as soon as possible. Because of the time zone difference there may be a delay in adding room nights to these dates. We apologize for any inconvenience. If you have any further questions or concerns please contact agenda@xxxxxxxx. We will update the community as soon as we can. Please also reference the IETF 100 hotels page https://www.ietf.org/meeting/100/hotel.html for information regarding our overflow hotels. Best Regards, IETF Secretariat
