Infrastructure

This page functions as a design specification for the network infrastructure: it describes the technical principles that guide how all2all builds, operates and maintains its services.

all2all operates hosting, mail, DNS and network services on infrastructure designed for independence, continuity and direct technical control.

The systems are based on free and open-source software, with Debian GNU/Linux as a long-standing foundation.

Operating principles

The infrastructure is managed with a preference for clear, maintainable systems:

• open standards
• documented configurations
• redundant network paths where needed
• direct control over routing and services
• avoidance of unnecessary platform lock-in

Network autonomy

all2all operates its own autonomous system, AS44312, under Moving Art Studio ASBL/VZW. This means that routing and IP resources are managed directly rather than only resold through a larger platform.

The organisation is a RIPE NCC member and Local Internet Registry. The network is operated from professional datacenter facilities in Brussels, with independent transit capacity and routing handled through BGP.

Hosting environment

The shared hosting environment is designed to support both simple publishing workflows and more advanced technical use.

It can provide web hosting, mail, databases, SSH access, version control tools and development environments depending on the selected service.

Network continuity

The network is maintained with attention to single points of failure, routing continuity and operational clarity.

Legend:

• two Linux edge routers
• two redundant core switches
• three bonded links from each router to the core layer
• aggregated 20 Gbit DAC ring
• BGP, eBGP and iBGP handled on Linux
• shared default gateway in high availability

Infrastructure choices are made to keep the service understandable, repairable and resilient over time.
