Any twitter admins here?

Hi All,

Does anyone here work for Twitter, or have contact details of anyone who
might.

We're a large organisation who look after the network for another large
organisation who are using Twitter in their broadcast promotions.

Unfortunately our network has been blocked from accessing Twitter and
their support cases require twitter for updates, so any contact details
would be gratefully received.

Thanks in advance

Thanks,

That unfortunately redirects to twitter.com, where we're blocked.
