Teraswitch identified a brief impact to network connectivity at our DUB1 and DUB2 sites beginning at 23:43 UTC. Undersea cables from both London and Amsterdam were lost, resulting in the brief loss of backbone and Internet connectivity at DUB1 and DUB2. Traffic was quickly restored via Internet routes and backbone connectivity via London followed shortly thereafter. Repair of the Amsterdam cable is also underway. Teraswitch is monitoring to confirm stability at these sites and will provide an update in the event of any further issues.
