"ARRL Announces Logbook of The World® Systems Upgrade

Dear LoTW user,

ARRL’s Logbook of The World® (LoTW®) is the 2nd most popular benefit among members. It is also an extremely popular service internationally for non-members, as it is the primary means for providing confirmations for ARRL Awards, such as DXCC and Worked All States.

As a part of the ongoing modernization of the ARRL systems infrastructure, LoTW will be receiving major upgrades to the operating system it is running on, the relational database system it uses to store and access logbook and awards data, and server hosting, where it will be fully migrated to the cloud. These changes will, among other improvements, ensure LoTW performance needs can be better met based on user demand.

LoTW will be unavailable from June 27 to July 2, 2025, to complete these upgrades. We will bring LoTW back online if it is available sooner than July 2.

Logbook of The World can be found at lotw.arrl.org. More information about the popular service is available at www.arrl.org/logbook-of-the-world.

If you are a user of LoTW and not an ARRL member, please become a supporter of LoTW by making a $20 (or more) donation to the ARRL LoTW Fund or visit www.arrl.org/donate.

Very 73, and see you on the air!

David A. Minster, NA2AA
ARRL CEO
