On all Linux, FreeBSD and OpenBSD servers, the SSH daemon is running and listening on port 22, root login is allowed with password or a pre-installed SSH key (rsa, dsa, ecdsa). Windows servers can be accessed via remote desktop over port 3389, using the assigned password found on the server info page ('Resources -> Servers' at ''). In the same place you'll find your servers IP addresses, and other useful information.

Yes, all G3 plans (with a region code of 3xx) fully support direct emailing over port 25, 465 and 587. To enable this feature, check the 'Enable SMTP' checkbox during deployment. SMTP support is a subscription based feature and cost $0.0137/hour.

Third party email forwarding services are accessible in all regions and supported by all plans.

Yes, this is done either via api or the control panel at: Supported formats include KVM qemu, VirtualBox, VmWare, Microsoft VHD(X), iso and more.

99Stack Cloud API is an advanced, fast and secure way to create and manage your resources. Every single aspect of your account and it's subscriptions can be managed from the API. Go to 'Resources -> API Docs' for more information. The control panel is fully built on the API and covers most of it's features.

We offer, Linux (Ubuntu, Debian, Centos, Arch, Alpine and some more), OpenBSD, FreeBSD and Windowes server 2012, 2016 and 2019. Custom ISO's can be uploaded and deployed via API in most regions, or mounted as virtual ISO for installation or recovery.

Yes, all plans and software images includes full root/administrator access. See 'Acceptable Use Policy' for information about legal restrictions.

Yes, all regions are IPv6 ready and at least one IPv6 address can be assigned to every server instance (/64 block), without additional cost.

Yes, all regions support private networks. Private networks are limited to server instances within the same data center. Data sent over the private network interface does not affect your plan transfer quota. In some regions you can also create your own private networks in order to divide your servers further.

Limited regions also support the deployment of VPC's for additional security on the private network interface.

Block storage volumes is available in all regions and dynamically scalable between 10GB and 15TB. Attach them to your server instance and treat them like a regular locally attached disk for additional storage. Encryption and all file systems are supported.

Object storage (S3 compatible) is available in limited regions. Files are stored on storage optimized managed instances powered by open source S3 compatible software.

This depends on your region, generation and for a few small plans with shared cores, the load of the physical host node. CPU frequency varies between 1.8GHz (low end standard instances) and 3.6Ghz (compute and dedicated). If you run Linux or BSD, you can use: lscpu | grep 'CPU MHz' to get the CPU frequency of your instance.

Server generations is a division between underlying providers or legal jurisdictions, and serves no technical differences. Some generations may provide an advantage over others for specific tasks because of technical limitations. But in most cases it's good enough to simply consider the generations as availibility zones.

More info:


Current balance can be found on the control panels main page, located at ''. An estimation of current usage can be found on the same page as well. The estimation shows the date and time when the account will run out of funds, based on current usage. Email reminders will be sent 14, 7 and 3 days in advance if the account has active subscriptions.

Most plans has a bandwidth cap, which tells you how much data is included in your plan. When this limit has been reached, different actions will be taken depending on data center and server generation:
  • Gen 1: Bandwidth overage is charged at $0.05/GB
  • Gen 2: Bandwidth overage is not charged, but you will get a slower link speed
  • Gen 3: Bandwidth overage is charged at $0.05/GB
  • Gen 4: Bandwidth overage is charged at $0.05/GB
  • Gen E11: All bandwidth usage is charged at $0.04/GB
  • Gen E12: All bandwidth usage is charged at $0.06/GB

Accounts are initially limited to 20 server instances. We'd be happy to increase your deployment limit at any time. Contact support, and let us know in which region you plan to deploy and what server type you prefer, to have this limit raised. An alternative way to raise deployment limitations instantly, is to deposit cryptocurrency to your balance. For every $20 deposited, your account is granted one additional server slot instantly.

All active subscriptions on your account are billed on a hourly basis, from a pre-paid balance. Payments are instantly deducted from your balance once a resource is created. Billing stops immediately once a resource is removed.

Yes, servers in a stopped state continue to reserve dedicated system resources (RAM, SSD storage, IP addresses, CPU), and will therefore continue to incur charges until you remove the server. The page: 'Billing -> View invoices', in control panel '', shows active subscriptions marked as green.

For every server type we offer, you have the ability to pay up front to save money. The discount is calculated on the hourly price and applies to the entire lifetime of the server. The longer you reserve a server for, the more discount you get.

After the prepaid amount has run out, you continue to pay the discounted price, no matter how long you decide to keep the server afterwards.

If you decide to cancel a pre paid subscription before its expiration date, the server will switch back to it's original price.

Due to the privacy friendly nature of our service, we're unable to determine who would be eligable for a free trial (new customers), or not eligable (returning customers). Therefore we cannot offer a free trial. However, we use hourly billing and allow withdrawals of unused funds, which makes it simple to try out the service for a minimal cost.

We accept all major credit/debit cards via Stripe and multiple Cryptocurrencies via Coinpayments, such as Bitcoin, Ethereum, Monero, Dash, Litecoin, Dogecoin and more.

Once your account no longer has enough funds to cover the cost of your running resources and active subscriptions the system will automatically start to purge everythnig.
