Resolved on January 28, 2026, affecting Intra-Market Connectivity and Ultra-Low Latency Connectivity.
At 2PM UTC, Teraswitch reloaded software related to our route servers to fix "stuck" transport tunneling sessions. This may have caused interruptions to ULL/HFT and transport services over our network. We believe the first stuck session started approximately 6 hours before, with more dropping off over the next few hours. As of this moment, all stuck sessions appear to be resolved, and traffic is passing normally and via ULL links.
