Dear de.NBI Cloud Users,
We are pleased to announce that the core de.NBI Cloud services in Berlin are available again.
We want to extend our sincere apologies for the lengthy delay in bringing our services back online. We understand the significant impact of this extended outage and are grateful for your continued patience.
The primary cause of the delay was an unexpected network issue related to a rate limit in an external switch, which prevented our services from being accessible reliably. Our team has been working continuously to resolve this and has now stabilized the environment.
Next Steps: Reconnecting Your Services
To restore public network access to your projects and virtual machines (e.g., SSH access), several steps are now required. Please perform the following actions in our dashboard: https://denbi-cloud.bihealth.org
1. Create a New Router
You must create a new router and connect your internal project network to the external network (e.g., public or dmz).
Instructions: https://cloud.denbi.de/wiki/quickstart/#creating-a-router-and-a-network
2. Allocate and Associate New Floating IPs
The old Floating IPs are no longer valid. You must allocate new IPs and associate them with your VMs. We now offer two types:
Public: For secure management via SSH through our jumphost: jumphost-01.bihealth.org. These are not directly exposed to the internet.
DMZ: For public-facing services (e.g., web servers). These are directly accessible from the internet on ports 80 (HTTP) and 443 (HTTPS).
3. (Optional) Reconfigure Load Balancers & Update Public DNS
If you use a load balancer, you must allocate a new dmz Floating IP and assign it to the load balancer to restore public access. Remember to update your public DNS records to point to the new IP address.
4. Start Your Instances
Once the networking is configured, you can start your instances again.
5. Update DNS Nameservers in Instances
After starting your instances, edit their nameserver settings (typically in /etc/resolv.conf on Linux) to ensure they can resolve domain names:
Remove old IPs: 172.16.106.4 and 172.16.106.5
Add new IPs: 10.57.196.4 and 10.57.196.5
Status of Remaining Services
Please be aware that we are still working to restore the following services:
SimpleVM
Shared File Systems (Shares / Manila)
Kubermatic KKP
Restoring these is our highest priority, and we will send another update as soon as they are available. If you have any questions or encounter issues, please contact us at denbi-cloud@bih-charite.de.
Best regards,
The de.NBI Cloud Berlin Team
