This event affected many customers
While performing a proactive maintenance on the infrastructure to increase security and improve resilience to malicious attacks against our network, an incorrect configuration command was entered on the border routers which started to gradually block legitimate traffic. As soon as the maintenance engineer was notified by our monitoring tool, the erroneous configuration was reverted, and connectivity was restored.
