Quick answer: Open a support ticket with your server ID and the port speed or traffic allowance you need. Upgrades such as moving from a 1G port to 10G or 20G connectivity depend on the location and your server's network hardware — support confirms availability, price and the switch-over window.
Overview
Two different things get called "bandwidth": the port speed (how fast data can move at peak, e.g. 1 Gbps) and the traffic allowance (how much data you may transfer in a month, if your plan meters it). Decide which one is limiting you before requesting an upgrade — the fixes are different.
Before you start
- Traffic statistics from your monitoring (or ask support for port graphs) — peak Mbps and monthly volume.
- Whether the bottleneck is peak speed (slow bursts, saturated port) or monthly volume.
- Expected growth for the next months, so you upgrade once, not monthly.
Step-by-step guide
- Measure your actual usage: peak throughput and monthly totals.
- Open a ticket: server ID/IP, current plan, requested port speed or traffic allowance, and when you can accept a short maintenance window if re-cabling is needed.
- Receive confirmation of availability and pricing for your location.
- Approve — the change is scheduled; port-speed changes may need a brief link renegotiation.
- Verify afterwards with a speed test between your server and a nearby endpoint (e.g.
iperf3).
Common issues
- Upgraded the port but transfers are still slow? The bottleneck may be the remote side, disk I/O or a single-threaded transfer — test with parallel streams (
iperf3 -P 4). - Only occasional spikes? A short-lived spike may not justify a permanent upgrade — consider a CDN or off-peak scheduling for backups.
- 10G/20G not available on your current machine? Older NICs may need a hardware change or migration to another server — support will propose options.
When to contact support
All bandwidth changes go through support. Also open a ticket if you see packet loss or lower-than-expected speeds without having hit your port limit — that is a network issue to investigate, not an upgrade case.
Frequently asked questions
Will the upgrade cause downtime?
A traffic-allowance change is seamless. A port-speed change may require a short link renegotiation, which is agreed with you in advance so you can pick a quiet window.
How do I know if I need more speed or more traffic?
Saturated bursts and slow peak-time transfers point at port speed; hitting monthly volume limits points at traffic allowance. Check your graphs before requesting the upgrade.
Is 10G available on my server?
Availability depends on the location and the network card in your configuration. Support confirms per server — older machines may need a hardware change or a migration.
