Odoo.sh has been intermittingly down for the past two days.

Very slow loading and then we get a banner with this message:

Odoo.sh Bad Gateway The server, while acting as a gateway or proxy, received an invalid response from the upstream server it accessed in attempting to fulfil the request.

Who do we contact about this?

I put in a help ticket on Odoo.com yesterday and have had no response.

Is this just us or do others have this problem?
