Infrastructure

We constantly extend our infrastructure to give you the highest reliability and ensure the best performance.

Enterprise-grade storage, no compromises! All of our hosting plans and limeDEDICATED servers run on super fast Solidigm D7 Series - the enterprise grade datacenter SSDs from Intel/Solidigm, which have performed great in all tests. These SSDs offer 1,100,000 IOPS with read access speeds of 7,100 MB/s and write access speeds of 4,200 MB/s. In combination with the new NVMe controllers we reach one of the best I/O performance currently available on the market.

We employ high-end enterprise grade hardware for all of our servers and take care that they are never overloaded. A standard that's far from common in the hosting industry.

Onlime gives your web applications superpowers!

Data Center

We operate our servers in the data center of METANET in Zurich, Switzerland. METANET has been proven as an extremely reliable housing partner. METANET provides us a fully redundant network and – as a RIPE-member under AS21069 – operates its own multi-10-gigabit-network.

Upon failure of a Cisco router the whole traffic is within a very short time completely taken over by the other; the same applies to the backbone connections. Additionally, METANET has direct connections to Cablecom, SWITCH, Google, and more than 30 other Swiss internet and content providers to provide their customers with the best access times. The remaining traffic runs over the two upstreams Interoute and Level3.

We operate our backup server infrastructure in the data center of the Nine, also located in Zurich. The infrastructure is installed in our own lockable quarter-rack in a highly secured colocation.

100% Switzerland! All servers are located in Switzerland, without exception.

The technologies we trust

Let us introduce some of the infrastructure technologies we fully trust and build our systems on:

How about our web dev stack?

Our Server Configuration

To be honest, we don't have to hide our system configuration. We invest in top-tier hardware so your sites run fast and stay online. For the tech guys among you — here are the current specs of our web servers:

Model	1HE Supermicro AS-1115CS-TNR
CPU	AMD EPYC 9634 84-Core 2.25GHz
Memory	512 GB DDR5 4800MHz ECC RDIMM
Disk	4x 3.2TB Intel SSD D7-P5620 NVMe
RAID	RAIDZ (ZFS RAID-5)
Network	1 Gbit/s redundant (LACP)

RAID

All SSDs run in a RAID-1 respectively RAIDZ (ZFS RAID-5) mirroring setup. If one SSD fails, the server continues to run undisturbed and the defective SSD can hot-swapped.

Failover

For each physical production server, we run an additional fallback server with similar hardware equipment, which in an emergency situation can take over at any time. For replication, we use ZFS snapshots.

Redundancy

All servers and infrastructure components operate in a fully redundant setup, both on network and on power level. In case of a failure of one component, the other takes over immediately and without any disturbance for our customers.

Off-site Backup

Our backup servers are operated in the colocation at Nine in Zurich. We create nightly full-system backups including all customer data, regardless of the hosting plan.

Offline Backup

In addition to the off-site backups we transfer all data to encrypted external drives on a weekly basis. These drives are stored each physically disconnected (offline).

Encryption

All data transfers, both inside the internal network of Onlime GmbH and to our external datacenter (off-site backup) is secured by encrypted connections.

Green IT

Onlime exclusively draws "naturemade star"-certified green electricity from EWZ (Elektrizitätswerke der Stadt Zürich). By choosing ewz.ökopower Onlime promotes the renewal and the construction of hydroelectric power plants to the highest ecological criteria. Also, the purchase of ewz.ökopower promotes the construction of additional solar power plants.

We operate our servers in the data centers of METANET and Nine. While METANET guarantees us green energy in the form of an eco-certificate, at Nine we choose the option "Ökopower" plus "Climate neutral operation" for entire compensation of CO2 emissions.

We also support Solarspar and ewz.solarzüri. Since 2014 we took a share in the construction and operation of a photovoltaic (PV) system on top of the school building Buchlern in Zurich.

While expanding our infrastructure and with each new server purchase we pay close attention to energy efficiency. We only use power supplies with 80plus Platinum (> 94%) certification and prefer components of the 'efficient-line' of our main supplier Thomas-Krenn.

1000% carbon compensation

Those three zeros are not a typo! In addition to the above commitment to green electricity and energy efficiency, we offset our total carbon footprint tenfold.

Via myclimate we calculate and offset the annual carbon footprint by taking the following factors into account: Workplace (heated area), electricity consumption (entire server infrastructure, workplace), travel to and from work by employees, business travel, meals, coffee/tea, materials and waste.
