Yes I agree, it seems a rather odd definition of 'storage server'.
I think of that as that's where my email data is stored, and the application servers (webmail, roundcube, etc) are separate to that, hence why it was working with roundcube but not for webmail.

Clearly runbox has a slightly different definition of it for their architecture.

I note webmail, imap and pop is currently busted again.
[Edit: the nodeping service tracker had this down, so not just affecting some accounts]

Thank you for keeping the status page updated, so I don't need to think, is it my end..

I hope you'll get a handle on this soon, as it seems to be the same recurring problem that you thought you'd sorted three days ago.
