Large DoS Attack

This afternoon at 12:15 PM a huge DoS attack was aimed at a customer on our Sonic Telecom CLEC network. The DoS attack was large enough to destabilize routing in our CLEC network, so customers may have seen 10-15 minutes of spotty connectivity as we tracked down and blocked the DoS. At this time, the attack has been blocked and all services are functioning normally.

    For the past two weeks I’ve been seeing packetloss of 50% or higher at times. Is this isolated to a single site or is it a random attack that keeps happening?

    Hi Brian,

    This attack would have only affected customer connectivity for roughly ten to fifteen minutes. If you’re still seeing problems, I’d suggest you get in touch with Support so we can help you troubleshoot.
