it is really strange if somebody in Iran face to a network problem that must be solve by a real NOC. however if any time you faced such a problem, you can take a look at this list – Network Operations Centers List -. you should find which one you are using , and then just contact them and hope to somebody responsible answer the phone !
one of the largest NOC is Global NOC located at Indiana University. it is managing extra large networks and systems like Internet2, iGrid and iVDGL.
