You initially asked this over a weekend when most of us were not working, so apologies for the slow response.
If you had any kind of existing whitelisting for the streaming API then you should already have had details of the email alias you could use to inquire about service status. If your application is not one that is associated with the Twitter account you’re using to post into this forum, please provide additional information (including Twitter account and application ID). In the meantime, I shall do what I can to investigate.
