Uploading extension failure / Service Status

Hi,

I've been working successfully with creating a VSTS extension. But 5h ago (and until now) I'm receiving this failure message after issuing tfx extension publish:

> tfx extension publish (parameters)

Failed Request: Not Found(404) - https://app.market.visualstudio.com/_apis/gallery

I guess that Microsoft is updating service or something but it is not spotted in service status page.

Any help is appreciated.

Thanks!
