Hey Jim, I just tried your query and it seems to be returning results. Could it have been a temporary condition? Have you been able to access this feed recently? It is possible that G could start blocking requests from YQL, however a 503 status code typically indicates a temporary server issue thus I would expect a different response if it was blocked.<br><br>--Josh<br><br><div class="quote "><div class="quotetop ">QUOTE<cite>(Jim G @ 10 Oct 2011 12:54 PM)</cite><blockquote class="quotemain">I've been using a query similar to <br><br><span style="font-family:Menlo, monospace;font-size:11px;line-height:normal;white-space:pre-wrap;">"<span class="console-formatted-string source-code" style="color:#c41a16;white-space:pre-wrap;font-family:Menlo, monospace;font-size:11px !important;">select * from atom where url='<a href="http://groups.google.com/group/rcog/feed/atom_v1_0_msgs.xml?num=50'&format=json&" class="webkit-html-resource-link" title="http://groups.google.com/group/rcog/feed/atom_v1_0_msgs.xml?num=50'&format=json&" style="color:#545454;cursor:pointer;max-width:100%;">http://groups.google.com/group/rcog/feed/atom_v1_0_msgs.xml?num=50'&format=json</a></span>"</span><br>to access Google Groups feeds.
