That XML error shows that your local scripts/java code is broken, not the Adobe link.
The second part looks like a real problem: http://community.adobe.com/chcservices/services/redirect?u=http://help.adobe.com&p=Photosh op_15.0&l=en_US&id=AH_HOME is not currently responding.
I have a suspicion that I know the cause: a power outage at Adobe headquarters has many of the internal servers shutdown right now. That link shouldn't depend on internal servers, but it looks like it somehow does.
