IONOS support ≠ server management: the difference that matters
IONOS (1&1 Ionos, United Internet AG) is a German hosting giant with over 8 million customers. Their strength: a comprehensive catalog (VPS, dedicated, cloud, domains, email) and accessible multilingual support. Their limitation: they are not an MSP — they do not manage your server.
What IONOS support does
- Phone support — a real advantage vs Hetzner/Contabo
- Hardware and network incidents
- Intuitive Cloud Panel for basic management
- Plesk/cPanel integrated as an option
- Datacenter in France (Lannion)
What IONOS support does NOT do
- No overnight on-call support — no proactive intervention at night
- No application monitoring or alerting
- No OS updates or proactive security patching
- No operational maintenance or disaster recovery plan
- No contractual SLA response time — it is "best effort"
What RDEM Systems adds to your IONOS servers
Keep the comfort of IONOS support for billing and hardware. RDEM handles everything above the hardware layer: OS, services, security, monitoring.
Proactive 24/7 monitoring
Agents on every IONOS server: CPU, RAM, disks, critical services, SSL certificates, response times. Alerts before the failure — what IONOS support does not do.
On-call support — 1h to 4h SLA
Contractually guaranteed response: 1h (critical) or 4h (standard), 24/7/365. IONOS support operates on a "best effort" basis with no time commitment — in contrast, our 24/7 coverage with a 4h SLA is staffed by a reachable human team, not asynchronous ticketing.
Security & updates
OS patching (Linux and Windows), hardening, firewall, intrusion detection. IONOS provides the server, RDEM secures it and keeps it up to date.
Backups & disaster recovery
Automated backups, regular restore testing, documented recovery plan. Compatible with IONOS storage or external storage.
Windows Server & Linux
IONOS is one of the few hosting providers offering native Windows Server. We manage both: AD, IIS, SQL Server on Windows; Apache, Nginx, PostgreSQL on Linux. See how to back up Windows Server with Proxmox Backup Server.
Cloud Panel & IONOS API
Leveraging the IONOS Cloud Panel and their API for provisioning, snapshots and network management. We can supplement or replace Plesk/cPanel with our own stack.
IONOS products we manage
IONOS offers a comprehensive range: Linux and Windows VPS, dedicated servers, Cloud Cubes and managed solutions. We manage all of them.
IONOS VPS (Linux & Windows)
| IONOS VPS | vCores | RAM | Storage | Bandwidth | Use case |
|---|---|---|---|---|---|
| VPS Linux XS | 1 | 1 GB | 10 GB NVMe | Unlimited | DNS, VPN, dev/test |
| VPS Linux M | 2 | 4 GB | 80 GB NVMe | Unlimited | Website, CMS, CI/CD |
| VPS Linux XL | 6 | 16 GB | 240 GB NVMe | Unlimited | E-commerce, ERP, database |
| VPS Linux XXL | 12 | 32 GB | 480 GB NVMe | Unlimited | SaaS, high-traffic API, multi-service |
IONOS highlight: VPS include unlimited bandwidth at 1 Gbps and KVM virtualization with dedicated vCores (no shared CPU). Windows Server VPS are available with the same configurations, license included in the price.
Other IONOS products
IONOS Dedicated Servers — Performance and reliability
IONOS dedicated servers with Intel Xeon and AMD processors, enterprise NVMe storage, unlimited traffic. Customizable configuration via the Cloud Panel. Suited for demanding workloads: virtualization, databases, critical applications.
IONOS Cloud Cubes — Flexible on-demand cloud
IONOS cloud instances billed hourly, perfect for ephemeral environments, horizontal scaling or load testing. Provisioning in minutes via API or Cloud Panel.
IONOS Managed Server — The IONOS "managed" option
IONOS offers "Managed" servers with pre-installed Plesk and basic updates. Caution: this does not cover 24/7 monitoring, on-call support, hardening or disaster recovery. For comprehensive server management, IONOS Managed remains insufficient — that is where RDEM steps in.
IONOS Datacenters
IONOS operates datacenters in Europe and the United States, including one in France. All ISO 27001 certified.

What does high availability require at IONOS?
Two things decide what is achievable, and neither is up to you: a private network between your servers, and a movable public address. The first lets the cluster talk and decide; the second determines whether failover is visible from outside — and how fast.
At IONOS the answer depends on the range — and the gap is total
Two ranges share the same name and offer very different possibilities. The test that settles it: if your console offers Virtual Data Centers → LAN → IP Failover, the mechanism exists. If you only have Cloud Panel → Network → Public IP, it does not exist in that form.
On the Cloud range: an IP failover group
IONOS Cloud offers an IP Failover Group, and its documentation states that VRRP is supported there through Gratuitous ARP announcements. The principle: reserve a public IPv4 address, place both machines' network cards in the same public LAN, and declare them members of the group. From then on your own configuration does everything — election, health checking, announcements. IONOS does not monitor your service.
- • The address must be a reserved public IPv4.
- • IPv6 is not supported by failover groups.
- • If the firewall is active, VRRP has to be allowed: it is IP protocol 112, not a TCP or UDP port — a classic mistake that costs half a day.
On dedicated servers: Public Networks, with a caveat
IONOS offers Public Networks, public VLANs intended among other things for floating addresses, to which several servers can be connected. However, their documentation does not explicitly guarantee that VRRP works between two bare-metal machines on that product, and those addresses are primarily intended for virtual machines hosted on the servers. The coherent design is therefore a hypervisor on each side and two front-end VMs connected to the Public Network — not the two physical hosts directly.
What we have not done yet
We have studied these mechanisms, we have not yet deployed them in production at IONOS. We would rather write that than imply field experience we do not have: if IONOS is your provider and the subject matters to you, we will start by validating the real behaviour before committing to a failover time.
Going further: the four architectures we deploy are compared by failover time and cost on our managed high availability page. Configuring VRRP and its traps are covered in keepalived or Pacemaker.
Our recommendation: Proxmox VE on your IONOS server
As part of our managed service, we recommend installing Proxmox VE (free, open-source) on your IONOS dedicated server. Proxmox VE can be installed via KVM console on IONOS dedicated servers.
- Native PBS backup: automatic VM backup to NimbusBackup, offsite at Equinix Paris — included in your managed service contract
- Snapshots before every update: instant rollback in case of issues, without downtime
- Service isolation: each application in its own VM, no domino effect in case of a vulnerability
- Live migration: move a VM from one server to another without downtime (useful when changing IONOS plans)
- No license cost: Proxmox VE is 100% open-source, unlike VMware. Proxmox support licenses are available and recommended for business-critical environments.
Already running Proxmox VE on your server? Perfect, NimbusBackup integration is immediate. Running bare Linux/Windows? We handle the migration to Proxmox VE as part of onboarding.
Learn more about Proxmox VEServer management, administration, operations: what each word covers
Depending on who you ask, the same work is called managed services, server management, server administration, operations or maintenance in operational condition. These are not five offers: they are five ways of naming distinct acts, which we perform on your IONOS servers at different frequencies and under different commitments.
The table below gives, for each term, the actual act, its frequency and the plan that covers it. This is the scope we sign.
| Term used | What we actually do | Frequency | Plan |
|---|---|---|---|
| Monitoring supervision |
CPU, RAM, disk fill level, network, application services and TLS certificate expiry — on a VPS, a Cloud Cube as much as on a dedicated server. Every alert goes into PagerDuty. | Continuous — 7am-10pm 7 days a week on Essential, 24/7/365 on Pro and Critical | All three |
| Preventive maintenance | OS and package updates, CVE remediation, log rotation and cleanup, certificate renewal, heading off disk saturation before it happens | Monthly cycle, plus critical CVEs handled off-cycle | All three — drawn from your included or prepaid hours |
| Corrective maintenance | Diagnosis and service restoration after an incident: a stopped service, a full partition, abnormal load, a server that does not come back and has to be taken over through the Cloud Panel console | On event, within a 4h response time (GTI) on Pro, 1h on Critical | All three — drawn from your included or prepaid hours |
| Server administration | The changes you ask for: accounts and keys, vhosts, firewall rules, certificates, adding a volume, changing a private network in the Data Center Designer | On request, scheduled with you | 1 hour per month included on Pro and Critical, then €120 excl. VAT per hour billed in 30-minute steps — you are warned before you go over |
| Operations | Backups pushed off-site to our Proxmox Backup Server at Equinix Paris, outside IONOS infrastructure, and restores actually replayed on a randomly picked machine, with the report handed to you | Daily backup; restore test once per half-year up to five machines, once per quarter beyond that | All three — capacity varies by plan |
| L2 / L3 support | There is no level 1 here: your request reaches a systems engineer directly, with no qualification script in between. Hardware replacement and physical work in the datacenter remain IONOS's job. We open the ticket on your behalf and follow it through: IONOS support answers a hosting question, not a system diagnosis. | Email and member portal during business hours; PagerDuty for a confirmed production outage | All three |
Maintenance is counted in hours, not in acts. Keeping a server in operational condition is capped by a volume of hours: those included in your plan, those you have prepaid, or those billed beyond. In practice, one hour per server per month covers routine needs — that is the volume included in the Pro and Critical plans. Beyond it, the hour is billed at €120 excl. VAT in 30-minute steps, and we tell you before you go over rather than after.
This scope is identical on an IONOS VPS, Cloud Cube or dedicated server: it is engineering time, not a percentage of what the machine costs. It applies just as much to a server we install as to taking over an existing server already in production and still held in your own name — see what you keep and how you get us out.

Incident triggering via PagerDuty
In case of a confirmed production outage, you trigger an incident via PagerDuty (credentials provided upon contract signing). Our on-call team is alerted immediately.
Legitimate incident:
- Server unreachable
- Critical service down
- Ongoing data loss
- Suspected security breach
Not an incident → email:
- Non-urgent technical question
- Planned change request
- Minor slowness with no business impact
Abusive triggering outside of production outages: EUR 100 excl. VAT per incident. This policy ensures on-call availability for genuine emergencies.
Your backups should not stay at IONOS
IONOS backups remain within the IONOS ecosystem — same single point of failure.
With your RDEM managed service contract, a managed offsite PBS volume is included: your Proxmox VMs are automatically backed up to our Equinix Paris infrastructure, physically separate from IONOS.
Essential
