Issues with connectivity through CoreSite & Voxel in LAX (help!)

Hi all, We're having a hell of a time at the moment, with upstream connectivity issues for traffic going through Voxel in LAX. We're a few hops away (our provider peers with CoreSite who peer with Voxel), and aren't having much luck getting assistance on getting this resolved. We're 8 hours in to these issues. If there's anyone from CoreSite or Voxel about that could reply off list, can provide additional info and would be super grateful. Thanks, Chris Boulton Bigcommerce
