I'm not really sure about exact number of application running in the environment as the client is a giant company spreading in US, UK and NL. There are 143 UNIX/Linux (AIX, Solaris and RHEL) servers dedicated for different things. This particular server hosts only one application. The research group is the end users of the application. They access it through Citrix. The app admin team is a different group. Problem is that the end users do not differentiate among the teams. To them, we are all IT people with weird techie-terms. That's why I got blamed for taking 24 hours to fix the issue. Whereas the actual people who should be blamed is the app admin team for not responding to my calls/E-mails.

You are right! Will just do what I'm paid for.
