Sametime Gateway federation with Google not working

Last week I started seeing problems with the s2s federation with Google, errors like the following were appearing in the SystemOut.log.

[12/03/13 17:24:43:112 GMT] 0000003b LoggableInput 3 com.ibm.rtc.gateway.xmpp.util.LoggableInputStream read(byte b[], int off, int len) XMPP logging < : length=203 msg:<presence to=”ben.williams@chooseportal.com” from=”hoagieben@gmail.com” type=”error”><error code=”503″ type=”cancel”><service-unavailable xmlns=”urn:ietf:params:xml:ns:xmpp-stanzas”/></error></presence>

It looked like Google were building white lists with approved domains. A friendly guy in IBM Support told me that there have been some changes in the Google policies and IBM are trying to “reach out” to Google in order to get a formal response and rectify these problems.

I read an article posted today called Google expected to unify chat under the name Babble and am thinking whether this is the beginning of the end for Gateway and Google federation?
