Bandwidth and uplink

Each configuration comes with a port speed: 1, 10 or 25 Gbps depending on the model, with higher tiers up to 200 Gbps available on request. Traffic on that port is unmetered. There is no per-gigabyte charge and no egress billing, so the port speed is the only limit that applies.

What unmetered means in practice ​

Unmetered is about volume, not about speed. A 1 Gbps port sustained for a month is roughly 320 TB, and none of it is billed. What it does not mean is that a single transfer will reach the port speed: one TCP connection over a long path is limited by latency and window size long before the port is.

Measure it properly ​

Use iperf3 between two machines you control, with several parallel streams:

# on the receiving server
iperf3 -s

# from the client
iperf3 -c 203.0.113.10 -P 8 -t 30       # 8 streams, 30 seconds
iperf3 -c 203.0.113.10 -P 8 -t 30 -R    # reverse direction

Test both directions. Inbound and outbound do not share the same path, and a problem on one is invisible on the other.

What not to conclude from a browser speed test: it measures one path, at one moment, through one intermediary, usually on a single connection. It is fine as a smoke test and useless as evidence.

Where your traffic goes ​

Transit and peering are ours: direct sessions at France-IX and DE-CIX, plus IP transit on our own backbone. For a specific destination, the return path on lg.bullionet.com tells you more than any throughput figure.

Custom BGP sessions are available on request: announcing your own prefixes, traffic engineering, dedicated peering. Ask by ticket with your ASN and the prefixes you intend to announce.

Move to a higher tier ​

• At order time: pick the uplink in the configuration table.
• On a running server: open a ticket. Uplink upgrades are a change on our side and do not require downtime on yours.
