ARRL LOTW

System upgrade & temporary downtime

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!

About Logbook of The World®

Logbook of The World® -- LoTW® -- is a web-accessed database and repository that enables you to submit electronic logs for amateur radio contacts (QSOs) and for confirmation (QSLs). Users can view submitted QSOs and resulting QSLs online. Radio amateurs can use LoTW to track their progress toward achievements and awards, such as The ARRL Worked All States Award, and amateur radio’s premier award, DXCC®, in which membership is achieved by confirming on-the-air contacts with 100 countries. LoTW was introduced by ARRL in 2003. Today, over 2.1 billion QSO records have been entered into the system.
