Good morning. We have received notice from AT&T who provides our Internet access to the headquarters facility that they will be performing a required security upgrade and reboot of their on-premise router. The work will be performed on Sunday 6/10/2018, during the maintenance window of 0400 to 1000 UTC. The actual upgrade of our unit should only take a few minutes, but it will happen anytime during the above stated window. The reboot will disrupt all internet access (including email, LoTW and VPN connections) at Headquarters during the actual upgrade process. All services will automatically resume as soon as connectivity is restored. The corporate website (www.arrl.org<http://www.arrl.org>) will not be impacted by this outage. Any orders taken on the website during the HQ outage should be queued and transmitted back after connectivity returns. 73, Barry J. Shelley, N1VXY Chief Executive Officer ARRL, Inc.
