Quick answer: Open a support ticket with your service ID, current usage profile (e.g. vnstat output) and the peak you need. Depending on the plan and location, the upgrade may be a plan option change, a port-speed upgrade (1G → 10G/20G on dedicated) or a custom arrangement — support will quote the options.
Overview
Bandwidth upgrades are routine, but the right mechanism depends on what you actually hit: the port speed (bursts flat-line at a round number like ~940 Mbps), a plan traffic allowance, or an application bottleneck that no port upgrade will fix. Diagnose first, then request.
Before you start
- Usage evidence:
vnstat -hpeaks, monitoring graphs, or iperf3/wget test results. - Your growth estimate — one-off event (sale, launch) or a new permanent level?
- Your service ID from the Client Area.
Step-by-step guide
- Confirm the network is the limit: flat-topped graphs at ~940 Mbps (on 1G) during peaks = port-bound; slow but not flat = look at other causes first.
- Collect the evidence (vnstat/graphs, dates, times).
- Open a ticket: service ID, current peaks, required peak, whether temporary or permanent.
- Support replies with the available paths: configurable-option change, port upgrade (dedicated: 1G → 10G/20G where available), or plan migration; pricing depends on location and configuration.
- Confirm; port changes on dedicated servers may need a short maintenance window — agree the time.
Common issues
- Upgrading the port when the app is the bottleneck — a PHP site doing 200 Mbps of dynamic pages won't go faster with 10G.
- Requesting "unlimited" — describe real peaks instead; concrete numbers get concrete quotes.
- Last-minute requests before a big event — hardware changes need lead time; ask a few days ahead.
When to contact support
This entire operation goes through support — there is no self-service port upgrade. Include the evidence up front and the ticket resolves in one round-trip instead of three.
Frequently asked questions
How do I know I really need more bandwidth?
Your traffic graphs flat-top at the port speed during peaks (about 940 Mbps on 1G). If the graph is not flat, the bottleneck is elsewhere.
What should the ticket include?
Service ID, current usage evidence (vnstat or graphs), the peak you need, and whether it is temporary or permanent.
Does a port upgrade cause downtime?
On dedicated servers a physical port change may need a short maintenance window — support agrees the exact time with you so the interruption lands off-peak.
