It seems we are hitting resource quotas two days at a row, we made a ticket and have to wait until business hours starts in Europe. We suspect an attack, our provider automatically suspend accounts under attack when resource are consumed extremely high. As soon as our websites are unsuspended we will investigate what has been going on and take all necessary actions. We just moved to this Cloud so this is new to us and completely unsuspected.
Update april, 21 2017 10:55 am CET:
The systems automatically suspended our account due to excessive use of resources. We are investigating and meanwhile the websites affected are online again.
Sorry for the inconvenience,
