When uptime is the requirement, not the goal.
Mission-critical workloads need more than a support contract. They need an on-call rotation that engineers answer in 15 minutes, an NOC that operates out of infrastructure under our control, and audit evidence that satisfies NIS2, KRITIS, and your insurer. That's what 24x7 Service means at Sysfacts.

Own-staff coverage
Why "real 24x7" is rare
Most 24x7 contracts don't survive a 3 AM test.
Four reasons what's marketed as 24x7 often is not.
Proxmox's own support is 8x5 CET
By design. Proxmox Server Solutions provides ticket-based enterprise support during Austrian business hours. Useful, but not a 24x7 service for KRITIS workloads.
"24x7" often means 8x5 plus emergency phone
Most "managed Proxmox" providers staff 8x5 with junior engineers and an after-hours emergency line. Mean time to engineering action: hours, not minutes.
SaaS-based NOCs fail when SaaS fails
If your monitoring, paging, and ITSM tools are all SaaS, an outage at the SaaS provider takes your NOC offline. A real 24x7 NOC needs infrastructure under direct control.
Audit evidence is rarely produced systematically
NIS2, KRITIS, ISO 27001 Annex A.5.30 demand evidence of operational continuity — not promises. Most providers produce this manually, if at all. Auditors notice.
What 24x7 Service includes
The premium-tier specifics.
Beyond the broader Managed scope, the Critical tier adds these commitments.
15-minute P1 response
Contractual. Measured. Monthly P1 response report included in the audit pack.
Engineering on first contact
No L1 triage. The on-call engineer is a senior infrastructure engineer with full Proxmox, storage, and network depth.
Quarterly DR drills
Failover tests scheduled and unannounced. Documented results. Improvements tracked through to closure.
Audit evidence pack
NIS2 / KRITIS / ISO 27001 evidence delivered monthly: uptime, restore tests, change log, access log.
Dedicated service manager
Single point of contact. Monthly reviews. Quarterly architecture revisits.
NOC out of FRA15
Our infrastructure, our runbooks, our keys. See FRA15 details below.
What Sets us Apart
3 nodes × 10 networks = 30 things that must stay in sync.
Without SDN, every cluster node maintains its own bridge, VLAN, and firewall configuration. Adding a node means replicating 10–30 entries by hand — and hoping they don't drift over time.
Without SDN
Node 1
vmbr0, vlan10, vlan20… (10 entries)
Node 2
vmbr0, vlan10, vlan20… (10 entries)
Node 3
vmbr0, vlan10, vlan20… (10 entries)

An all-inclusive Backup & DR assurance package. Built for audits, insurers, and executives.
Sysfacts Assurance turns Backup & DR into a reliable corporate insurance policy: governance-driven, audit-ready by design, technically implemented, and continuously validated.
Monitoring & alerting across the Backup/DR chain
Without clearly defined recovery targets and regularly tested recovery, even a short disruption can escalate into lost revenue, operational standstill, audit exposure, and reputational damage.
Recovery tests per plan + evidence (protocol/certificate)
Without clearly defined recovery targets and regularly tested recovery, even a short disruption can escalate into lost revenue, operational standstill, audit exposure, and reputational damage.
Findings-to-remediation management
Without clearly defined recovery targets and regularly tested recovery, even a short disruption can escalate into lost revenue, operational standstill, audit exposure, and reputational damage.
Monthly reporting (KPIs, status, risks, action tracking)
Without clearly defined recovery targets and regularly tested recovery, even a short disruption can escalate into lost revenue, operational standstill, audit exposure, and reputational damage.
Offsite storage / immutability options (architecture-dependent)
Without clearly defined recovery targets and regularly tested recovery, even a short disruption can escalate into lost revenue, operational standstill, audit exposure, and reputational damage.
Fully managed backup operations (run & optimize)
Without clearly defined recovery targets and regularly tested recovery, even a short disruption can escalate into lost revenue, operational standstill, audit exposure, and reputational damage.
Example of why this is critical:
If you have an automated high-bay warehouse, a backup from midnight today won't be of much use to you at 8 p.m. today because so many movements have taken place in the warehouse in the meantime that the 20-hour-old data is worthless. You have to look at this from a business perspective and “snatch” it away from IT.
What Sets us Apart
Sysfacts developed the Critical Transition Method—a systematic approach to managing IT transitions without disruption.
It combines proven processes, AI-supported tools, and senior experts who take full responsibility from decision to stabilization. CTM isn’t theory. It’s a method built from hundreds of real-world projects — tested, measurable, repeatable.
Transition readiness check
We audit your environment, identify all dependencies, and assess the specific risks of Windows Server 2012 EOL. We check: Which applications are running on which servers? Which interfaces exist? Where are the compliance risks?
Transition & Architecture Design
We develop the target vision (Windows Server 2022, cloud migration, or hybrid), the detailed migration plan, and define clear roles and responsibilities. We plan downtime windows and create the decision template for your management.
Implementation support & hypercare
We manage the implementation, monitor the critical transition phase, respond to unplanned events, and hand over stable, documented operations.
Are you facing a complex IT transition?
Find out in just a few days how your transition can be secure, fast, and budget-friendly with our Transition Readiness Check (TRC).
Speak directly with a senior Sysfacts architect about your current system, upcoming changes, and possible transition scenarios.
Backup is not an IT topic. It’s a board-level insurance decision.
Protect your business against downtime, ransomware, and audit risk.
Data is the heartbeat of your business — and losing it can mean losing everything. From ransomware and accidental deletion to natural disasters and cloud outages, threats to your business continuity are everywhere. The question isn’t if something will happen — it’s when.

Why CFOs and legal teams choose Sysfacts Assurance
Sysfacts Assurance gives CFOs and legal teams something rare in Backup & DR: clear accountability, audit-ready evidence, and proven recoverability that stands up to insurers and authorities.
KPIs and Evidence (Assurance Proof)
Sysfacts Assurance tracks a focused set of KPIs to continuously prove recoverability and readiness. These cover backup reliability, recovery test coverage by tier, documentation freshness, failure detection speed, and the resolution of identified issues, giving management a clear view of operational risk at all times.
The Evidence Pack provides audit-ready proof of recoverability, including restore test results, test certificates, a versioned DR strategy with decision logs, and a complete action history. It can be handed directly to auditors, insurers, or authorities without additional explanation.
Sysfacts Assurance shifts Backup & DR from an IT task to a management-approved risk decision, creating defensible accountability for executives and legal teams.
Risk-based tiering connects recovery requirements with economic impact, allowing management to define how much protection is needed and what it is worth.

24x7 Service FAQ.
Lorem ipsum dolor sit amet, est mollis iuvaret officiis ne, magna idque mentitum ei nec, iisque convenire similique cu sit.
Yes. We do scheduled but unannounced escalation drills as part of our internal QA, and we encourage customers to do their own. The numbers we publish (7 min mean time to engineering action) are measured across real incidents and drills combined.
Monthly evidence pack: uptime report, P1 response report (every P1 with timestamp, responder, resolution), restore-test artifacts, DR-drill reports, change log, access log. Format compatible with NIS2, KRITIS, and ISO 27001 audit requirements.
Yes. The transition takes ~4 weeks for paging, runbook, and escalation calibration. Pricing adjusts on the next billing cycle. We've never seen a customer transition the other way.
We open a case with the upstream vendor (Proxmox Server Solutions, hardware vendor, OS distributor) and provide a workaround if one exists. Our SLA covers response and best-effort resolution; vendor fix-time is outside our control. We document the case openly and pursue the vendor on your behalf.
Proxmox's own enterprise support is ticket-based, business hours, CET only — and excellent within that scope. Our 24x7 service complements it: we hold the upstream subscription with you, escalate to Proxmox where needed, and provide 24x7 operational coverage on top.
Make uptime contractual.
Most 24x7 engagements start with a 24x7 Health Check. The remediation list often pays for itself in audit findings closed before the service even starts.
