Many servers hosted on Contabo.com seem down, even their user dashboard is down: https://www.isitdownrightnow.com/my.contabo.com.html
But their status page, as all status pages, is showing everything is ok: https://contabo-status.com/
I don't think I've seen any status page from big companies in the last years that actually shows when there's an outage (probably marketing/PR/branding issues).
It looks like ALL their VPS are down. A bit strange that their user panel is down too, maybe it's hosted on their own VPS infrastructure.
I understand downtime happens, but communication so far is terrible with Contabo. There have been outages before and they were never registered in their status page.
EDIT: Seems like they added it on https://contabo-status.com

So, the next update is in 3 hours. That's a long downtime window.
