ARRL Systems Service Disruption


Updated 07/09/2024

As previously reported, ARRL® Logbook of The World® (LoTW®) returned to service on Monday, July 1, 2024. As anticipated, there was a significant rise in use to catch up on processing logs following the outage. It took 4 days for normal processing times to return.

The ARRL Radiosport Department has resumed processing applications for most awards. The systems for Worked All States (WAS), VUCC, and issuing credits for CQ WAZ and CQ WPX awards have returned to service. These award applications are being processed on a “first in/first out” basis.

WAS applications submitted through July 4 and VUCC applications submitted through July 1 have been processed. CQ awards applications are processed by CQ and not ARRL.

While we can process these ARRL awards and update records, the ability to print and deliver certificates, endorsements, and other material has not yet returned.

The online DXCC® application is unavailable at this time and DXCC awards are not able to be processed. Work continues to return the DXCC systems to service. All DXCC data is secure.

This story will be updated with new developments.

The ARRL Volunteer Examiner Coordinator Program continues to operate during the systems service disruption.

ARRL Volunteer Examiners (VEs) should continue to submit exam registrations and material requests. While we are unable to post new or revised exam session dates and details to the website, we can ship out exam materials. Please remember that most exam materials are available on our website ( We are processing Amateur Radio License applications to the FCC. The VEC exam session upload webpage was not affected by the incident. We are currently unable to create International Amateur Radio Permits, License Class Certificates, and Volunteer Examiner (VE) badges, certificates, and stickers. New ARRL VE applications and renewals are unable to be processed at this time.

ARRL is continuing to accept reimbursement forms to cover the one-time $35 application fee for new license candidates younger than 18-years of age for tests administered under the auspices of the ARRL VEC. Reimbursement checks may take longer than normal to be processed at this time. 

This story will be updated with new developments.

A comprehensive update on the status of ARRL VEC services is available here.

Updated 07/01/2024

Effective 12:00pm ET / 16:00 UTC we will be returning Logbook of The World® (LoTW®) to service. 

As work progressed on the network, some users encountered LoTW opening briefly during which some 6600 logs were uploaded. The logs were not processed until this weekend as we tested that the interfaces to LoTW were functioning properly.

We are taking steps to help manage what will likely be a huge influx of logs. We are requesting that if you have large uploads, perhaps from contests or from a DXpedition, please wait a week or two before uploading to give LoTW a chance to catch up. We have also implemented a process to reject logs with excessive duplicates. Please do not upload your entire log to “ensure” your contacts are in LoTW as they will be rejected. Lastly, please do not call ARRL Headquarters to report issues you are having with LoTW. You can contact support at

Through the end of the year, you may experience planned times when LoTW will be unavailable. We have been using this time to evaluate operational and infrastructure improvements we would like to make to LoTW. Those times will be announced.

We appreciate your patience as we worked through the challenges keeping LoTW from returning to service. We know the importance of LoTW to our members, and to the tens of thousands of LoTW users who are not ARRL members. LoTW, just behind QST, is our second most popular ARRL benefit.  

This story will be updated with new developments.

ARRL staff continue to work with outside industry experts to ensure that all servers have been remediated, tested, and all data has been confirmed. We have also been working to ensure that the network is secure.

As noted in previous updates, Logbook of The World® servers and data are fine and working. LoTW® has dependencies on other servers, for example membership data, which have not yet been returned to service. We will announce when LoTW is open for user access. We anticipate that the queue will grow quite large once live, and we are evaluating ways to manage that potential issue.

As a reminder, 2024 ARRL Field Day is this weekend. We note that some groups have scaled back or cancelled their outdoor plans due to excessive heat or severe weather threats. Please use caution this weekend (visit for heat and health information). Enjoy Field Day. The Field Day bulletin will be transmitted from W1AW and K6KPH as scheduled (see PDF schedule). Your Field Day results may be uploaded to or mailed to ARRL after the event.

We are continuing to make progress on restoring the ARRL network and many related systems and databases. Thank you for your continued patience and understanding as we carefully address and restore affected services.

While the Logbook of The World® server, Online DXCC, and related user data are secure and unaffected, we have taken the precautionary measure of keeping the services offline until we can ensure the security and integrity of our networks.

The ARRL Learning Center (, our online course and training hub, is accessible. The Learning Center includes content from across a variety of amateur radio topics and interests. The Learning Center will require a slightly different login experience while we continue to restore interconnected databases. Users who have logged into the Learning Center before will need to use their EMAIL ADDRESS and use the 'forgot my password' function to set a new Learning Center password. Users who are new to the system will sign up/register using their email address. When ARRL systems are fully restored, user accounts will be reconciled with membership accounts again.

ARRL Field Day is June 22 – 23, 2024. Visit for rules and other resources to help prepare your participation. Following the event, online entries will be supported as usual at

The ARRL Volunteer Examiner Coordinator is continuing to process Amateur Radio License applications to the FCC. We have processed all applications from exam sessions uploaded by Volunteer Examiners through June 12, 2024. Sessions mailed to ARRL VEC and received by us are processed within 1 – 2 business days.

The new Amateur Extra-class Question Pool will be effective beginning July 1, 2024. New Extra-class exam booklet designs will be supplied to VE teams as soon as possible. Teams may also contact the ARRL VEC after July 1 for an emailed version in the interim.

Updated 6/4/2024

On or around May 12, 2024, ARRL was the victim of a sophisticated network attack by a malicious international cyber group. ARRL immediately involved the FBI and engaged with third party experts to investigate.

This serious incident was extensive and categorized by the FBI as “unique,” compromising network devices, servers, cloud-based systems, and PCs.

ARRL management quickly established an incident response team. This has led to an extensive effort to contain and remediate the networks, restore servers, and staff are beginning the testing of applications and interfaces to ensure proper operation.

Thank you for your patience and understanding as our staff continue to work through this with an outstanding team of experts to restore full functionality to our systems and services.

We will continue to update members as advised and to the extent we are able.
