Hi everyone, I have some more info on the downed nextcloud.com website:
On Sunday evening our website was defaced. We isolated the affected server immediately and we are still investigating what exactly happened.
Meanwhile our homepage has been restored from a backup on a new server.
We confirm that this breach could not affect any user or customer server, as our other services, like downloads or the Nextcloud App Store are on separate servers and unaffected.
We are continuing with our post-mortem analysis and will give further updates once we have more details.
