anyone from GBLX ?

anyone from global crossing internet linking company ?

If you are on the inoc-dba phone system, it is as easy as picking up a
phone and calling them.

They're listed in
https://www.pch.net/inoc-dba/console.cgi?op=show_pubdir&list=org

but the main problem is I am not in US...errrr.... how could I report
their network problem ?

Depends. If you are their direct customer I guess you know how to get
in touch with them. If your upstream provider gets connectivity from
GBLX, you might want to get them to escalate the issue.

ps - You don't need to be in the USA to use the inoc-dba phone system.
All you need is to be a network operator with your own AS.
