<p class="MsoNormal">On Saturday, 15 September 2012 ARIN will be
conducting
maintenance on back-end systems in order to upgrade the management
applications
for ARIN Online. The work will take place from 7:00 AM until
approximately 5:00
PM EDT. </p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">ARIN users will experience interruption of
three external
services while this maintenance is performed. For the duration,
you will not be
able to log in to your ARIN Online account. Any mail sent to
Registration
Services will be queued and not immediately acknowledged. </p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Additionally, transactions submitted via ARIN’s
RESTful
Provisioning service will be rejected with an outage error. Once
the systems
are back online, you will regain use of your ARIN Online account
and queued
mail will be processed. You will need to resubmit any RESTful
calls sent during
the outage so they can be processed.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">All other publicly available services (Whois,
IRR, etc.)
will be available during this outage.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Thank you for your patience and cooperation.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Regards,</p>
