Limits RegistryPUBLIC RECORD
Limits Registry2Africa, a submarine cable system led by a consortium including Meta, China Mobile International, MTN, Orange, Vodafone, and others, spans roughly 45,000 km — the longest subsea cable system in the world — and is designed for a maximum capacity of over 180 Tbit/s, among the highest of any subsea cable system as it entered service in phases through 2023-2024. Design capacity reflects the system's engineered ceiling; actual deployed and lit capacity is typically brought online incrementally as demand grows.

The published maximum design capacity of the 2Africa submarine telecommunications cable, a Meta-led multinational consortium project connecting Africa, Europe, and Asia via approximately 45,000 km of subsea fiber.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
