FAQ
Common questions
Short answers to what new customers ask us most.
Where is my data stored?
In BG‑SOF‑1, our own data center in Sofia, Bulgaria. Your data stays in the EU and is never moved to another country without your written agreement. Backup copies are kept on separate, isolated storage.
Can you migrate our existing servers?
Yes. We start with an assessment of your current systems, agree a plan and timeline with you, and move workloads in planned windows to keep downtime to a minimum. Physical servers can also move into colocation as they are.
What does your SLA cover?
Our SLA commits to 99.95% monthly availability and a 30-minute first response to P1 incidents, 24/7. If we miss the target, you receive service credits. The full terms are on our SLA page.
Is support available in English and Bulgarian?
Yes. Existing customers reach our NOC 24/7 through the Client Portal, for support and critical incidents. Sales and general questions sent through the contact form or to info@neboracloud.com get a reply within one business day. Either way, we work with you in English or Bulgarian.
How does billing work?
You receive one monthly invoice in euros for all services under a single contract. Cloud resources are billed by usage; colocation and managed services have a fixed monthly fee. Invoices and usage reports are always available in the Client Portal.
