We have been working with Sunucun Bilgi İletişim Teknolojileri for years and every time we see that we made the right choice. Their technical knowledge is truly top-level, and they are incredibly fast and solution-oriented, especially in emergencies. They don't just fix problems; they also improve the system so the issue doesn't happen again in the long run.

I have been using their Reseller Hosting service for 2 years. In that time I haven't had a single problem apart from one or two, and when those happened they solved them without leaving me in a difficult spot. I just got a dedicated IP for my hosting accounts' e-mail and I plan to renew the service at the end of the year. Thank you for the excellent partnership and service. I hope we keep working together for many years.

What to Prepare for a Quote

Colocation pricing depends on space, power and connectivity. Sharing the details below speeds up your quote.

  • Number of servers and network devices, and the U height of each
  • Total power draw (W or Amps) and number of power supplies
  • Required port speed (1 / 10 / 40 / 100 Gb/s)
  • IPv4 / IPv6 needs and whether BGP with your own ASN is required
  • Remote access details (KVM / IPMI / iDRAC / iLO)
  • Hardware delivery date and installation expectations

We Are Here to Help You!

Our expert support team is always at your service to help you move forward with confidence every step of the way. We are here to provide the fastest and most effective solutions to your questions.

Server hosting (colocation) means hosting your own servers and network devices in racks at a data center, with power, cooling and internet connectivity provided by the data center.

With hosting the hardware is yours and we provide space, power and connectivity. With server rental we provide the hardware and you pay a monthly fee.

Yes. Colocation and server hosting describe the same service.

Our server hosting service is provided at the MARS data center in Istanbul.

U is the unit of height in a rack (1U ≈ 4.45 cm). 1U is a single slim server, 21U a half rack and 42U a standard full rack.

The price depends on the space used (U), the power consumption of the devices and the port speed and IP needs. That is why colocation is quoted for your specific needs.

The number of devices and their U height, total power consumption and number of power supplies, the required port speed, IPv4/IPv6 and BGP needs and remote access (KVM/IPMI/iDRAC/iLO) details help us prepare your quote quickly.

1, 10, 40 or 100 Gb/s fiber uplinks are available. We can decide together which speed you need based on your traffic and applications.

Yes. BGP is available on hosting plans. If you do not have your own ASN, see our ASN lease service.

Yes. IPv4 and IPv6 addresses can be requested. For larger IP blocks see our IPv4 lease service.

Our network runs with a 100 Gb/s redundant uplink, multiple carrier connections, Juniper network devices and more than 150 peering points; the MARS infrastructure has 2.8 Tb/s of DDoS protection capacity.

It suits companies that own their hardware, use special hardware or network devices, run BGP with their own IP block and ASN, or want full ownership of their hardware.
