In computer networking, ingress is a term that usually designates traffic entering the organization’s network.

At Scalingo, ingress refers to the traffic coming from the Internet and entering the platform’s infrastructure.

Ingress IP Addresses

Our ingress IP addresses are the IP addresses through which incoming traffic enters the Scalingo platform. They are all externally reachable and act as an entry point IP for inbound traffic flowing from outside into the Scalingo network.

We have several IP addresses for each region.

Region osc-fr1

• 5.104.101.30/32
• 109.232.236.90/32
• 109.232.233.130/32
• 148.253.75.120/32

Region osc-secnum-fr1

• 148.253.96.193/32
• 185.21.194.105/32
• 80.247.12.255/32
• 80.247.13.145/32

Ingress Specifics

To reduce the attack surface of the platform and to protect our customers’ applications, we actively filter ingress traffic based on multiple criterias. The idea is to only accept traffic that seems acceptable. This also allows us to enforce some good practices.

Zero Cost

At Scalingo, there are no ingress fees. This means that all ingress traffic is free of charge.

Ports

We only accept requests targeting TCP port 80 (HTTP) and 443 (HTTPS). All ingress traffic targeting other protocols or ports is silently discarded.

If you use Cloudflare Proxy, TCP ports 80, 443, 8080, and 8443 are opened from your application’s point of view.

Denylists

We use denylists to filter out traffic originating from IP addresses known to spread malicious threats, take part of DDOS attacks, etc.

If you think an IP address is wrongly filtered out, please get in touch with our Support team.

Bandwidth

Network bandwidth is limited to 20MB/s per container (or 160Mbit/s). This limit comes with a burst of 1.6GB/s per container (12.8Gbit/s).

Max. Request Size and Uploads

The request size limit is set to 75MB. This limit is set on our frontend reverse proxies. A 413 Payload Too Large HTTP error is returned when attempting to overcome this limit.

If you have a bigger file to upload, please consider using a third-party storage facility like Amazon S3 (or any other provider) and upload files directly to it (with signed-URL for instance).

Max. Headers Size

The entire header section of a request is limited to a size of 32kB.
In addition, a single header is limited to a size of 8kB.
