LACNIC joins CaribNOG 32 in Curaçao to boost Caribbean network resilience
in plain words
LACNIC, the organization that manages internet addresses for Latin America and the Caribbean, joined a regional networking conference in Curaçao. Experts taught local internet providers how to keep their networks running during hurricanes, earthquakes or damaged undersea cables. They recommended using backup satellite links, security checks called RPKI, and getting your own internet address block instead of borrowing one.

LACNIC Latin America and Caribbean Network Information Centre The regional Internet registry for Latin America and the Caribbean. Full definition of LACNIC returned to Curaçao, part of its service region, for CaribNOG 32, held in Willemstad from October 7 to 9, 2026, under the theme “Ready for resilience: strengthening the Caribbean digital core.” The event gathered network operators, regulators, diplomats, IT managers and data centre staff from across the Caribbean.
On the opening day, LACNIC’s Alejandro Acosta presented updates on IPv6 adoption in the Caribbean, IPv4 waiting-list requests, the addition of ASPA to MiLACNIC, LACNIC Campus course news, and an invitation to LACNIC 46 LACNOG Latin America and Caribbean Network Operators Group The network operators' group of Latin America and the Caribbean, which meets yearly with the October LACNIC meeting.

The presentation was delivered jointly with representatives of ARIN American Registry for Internet Numbers The regional Internet registry for North America.

On the closing day, Acosta and ICANN’s Nicolás Antoniello, with an introduction from ARIN chief technology officer Mark Kosters, led attendees through router configuration exercises built around Caribbean-specific risks such as vulnerable submarine cables, hurricanes, seismic and volcanic activity, and the economic cost of outages.
Recommendations included prioritising fibre connections to at least one submarine cable, ideally more than one, with a satellite backup; using low-earth-orbit satellites for backup since they cut latency to 25–40 milliseconds versus 500–700 milliseconds for geostationary satellites, though a single LEO link cannot handle the traffic of many providers; multihoming with fibre carrying the full routing table and LEO used only as a default backup route; deploying RPKI-based route origin validation; using BGP features to automatically filter route leaks between declared providers and customers; enabling the BFD protocol, which cuts failure detection from about 90 seconds to milliseconds and is often offered free by providers on request; and allowing ICMPv6 through filters to support Path MTU Discovery, a common gap in the region.
Afternoon sessions let participants practise these concepts through labs covering resolver The DNS server that looks up domain names on behalf of users.
