2022 – LINX joined the long list of organizations supporting Ukraine by disconnecting Russian services from its networks. Technology In London, LINX operates two physically separate networks, or switching platforms, on different architectures using equipment from different manufacturers (Extreme Networks and Juniper Networks). These networks are deployed over ten locations, each connected by multiple 100 Gigabit Ethernet or 10 Gigabit Ethernet connections over fibre networks. The LINX Engineering team restructured its secondary LAN in London, LON2, in 2018 using software and hardware from two different suppliers. LINX data center facilities are found at sixteen locations throughout London, including: Telehouse North Telehouse North 2 Telehouse East Telehouse West Equinix Harbour Exchange (ex. TeleCity) Digital Realty, Bonnington House, Millharbour (ex. TeleCity) Digital Realty, Sovereign House, Marsh Wall (ex. TeleCity) Equinix Powergate, Acton Equinix, Slough Interxion London City Virtus, Hayes (Transmission PoP) Colt Data Centre, London West (Transmission PoP) Connecting is also possible from remote locations via the 'LINX from Anywhere' scheme via a range of layer 2 service/MPLS carriers. Redundancy of the network is managed using rapid-failover protection mechanisms such a VPLS service over an MPLS core (MPLS/VPLS) from Juniper and Extreme's Ethernet Automatic Protection System (EAPS). These restore connectivity within tenths of a second in the event of the loss of a network segment. In addition to the main peering infrastructure, LINX provides managed private interconnections (via Single Mode Fibre) between LINX members, and works with a number of fibre carriers to provide rapid connection between LINX members for private circuits. These PI circuits may be used for any purpose, but are mainly intended for Private Peering arrangements between members. Private Peering is sometimes more appropriate for managing large flows of traffic between ISPs and/or Content Providers. Telehouse hosts the vast majority of internet peering traffic from LINX. Public affairs One of LINX's core functions is to represent its members in matters of public policy. LINX's Public Affairs department works to obtain advance warning of public policy developments that could affect LINX members, to inform members about important policy developments at a time when it is still possible to influence them, and to educate, inform and influence regulators and legislators. At the UK level, LINX liaises directly with policymakers on matters such as content regulation, telecoms regulation, privacy and data protection, e-mail spam, online fraud/phishing, law enforcement, counter-terrorism, and any other topics that affect LINX members. At the European level, LINX
