Attention: Since a disk (SSD or SATA HDD) that contains data cannot be shrunk, additional space can only be cancelled by removing it together with all the data on the disk (for the system SSD, this means reinstalling the OS).

Price of additional snapshots:
For the S1, S2 and S3 plans, 1 additional snapshot costs 2 EUR/month; for the S4 and S5 plans, 3 EUR/month. The maximum number of snapshots per VDS is 5.

Price of additional traffic:
1TiB (1 000GB) of additional traffic costs 2 EUR/month on a prepaid basis. When ordered for the current month (or "until the end of the month"), 1TiB (1 000GB) costs 3 EUR.

Additional IP addresses:
1 additional IP address costs 3 EUR/month + 20 EUR setup fee. IP addresses are allocated subject to technical availability.

IP address change at the client's request:
Costs 5 EUR per change. The VDS will be assigned a new IP that differs from the current one (it may, however, be one it has used before). A guaranteed change to a new IP that has never been used before by this VDS or by the client's other (currently active) VDSs costs 10 EUR per change. The service is provided only subject to technical availability. The service is not available for the S4 and S5 plans.

Payment terms for additional resources and upgrades:
Additional resources are paid for a full month on the day of the order, regardless of the order date. After that, the VDS and the additional resources are paid for together.
Example: your VDS is paid until August 20. On August 15 (5 days before the end of the period), you order +1GB of RAM for 2.00 EUR/month. For these 5 days you pay the full monthly price of the add-on, 2.00 EUR. Then on August 20 you pay the renewal of the VDS + additional resources for the next month, until September 20.

Terms for cancelling additional resources:
The configuration is changed on the day the request is submitted. In case of early cancellation, the payment for the "unused" period is not refunded. Additional SSD / SATA HDD space is cancelled by reinstallation, with the loss of all data on the disk being reduced.

Attention: depending on the free resources available on the host node serving your VDS, the upgrade may require moving your VDS to another host node. This will change the IP address of the VDS (all data / files / OS settings will remain unchanged), and the minimum first payment for the upgrade will be 5 EUR.
For example: you order the "increase SSD to 130GB" upgrade for S6 for 3 EUR/month, but the current host node does not have enough free resources for it. Accordingly, the upgrade will require moving the VDS to another host node, and the first amount due will be 5 EUR instead of 3.
