ARRL Logbook of The World� (LoTW�)[1] returned to service July 1, 2024. It had
been offline as part of a systems service disruption[2].

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.

Despite this request, we have seen several recent DXpeditions upload large log
files and many amateurs have uploaded logs with excessive duplicates. This
negatively impacts the backlog time.

Lastly, please do not call ARRL Headquarters to report issues you are having
with LoTW. You can contact support at [email protected][3].

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[4], just
behind QST[5], is our second most popular ARRL benefit.�
