For the last 3 days, any attempt to reassign a subnet with the RESTful API results in the following error:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<error xmlns="http://www.arin.net/regrws/core/v1">
            <message>IP range overlaps with existing network(s).</message>
    <message>Payload entity failed to validate; see component messages for details.</message>

The subnet in question here is I have verified that there are no other subnet registrations in the adjacent space ( was analyzed and found to contain only subnets in "Direct Allocation".

My sample reassign payload is as follows:

<?xml version="1.0"?>
<net xmlns="http://www.arin.net/regrws/core/v1">

Has anything changed recently that would be causing this error? Is there some other underlying issue causing this?
