A Massive denial of service attack on a Dyn, a large DNS service provider, has been affecting many large sites this morning. This includes parts of Amazon’s infrastructure, Twitter, Reddit, Spotify along with many smaller properties. This attack results in errors like “Server not found” or “Host not found” in web browsers and other applications. For a more detailed account, please see https://www.wired.com/2016/10/internet-outage-ddos-dns-dyn/ or https://krebsonsecurity.com/2016/10/ddos-on-dyn-impacts-twitter-spotify-reddit/ and note, this affects more than just the East Coast.
Starting tonight at 6:15PM PDT we will begin blocking all UDP traffic at our network edge destined to port 1900 (SSDP) to mitigate DDoS amplification attacks from affected equipment.

Tonight, February 24, starting at 8:53pm, a large DDoS towards a collocation customer caused reachability issues for services hosted in our Santa Rosa data center. This malicious traffic has been blocked at our edge, and all connectivity has been restored.

This morning, at around 9:15AM, a DDoS attack towards Sonic.net owned equipment de-stabilized part of our hosting network resulting in the inability to access to the www.sonic.net website and some others. The issue has been handled and access to the sites restored as of 9:45AM.

Starting at about 2:24 PM today, a distributed denial of service attack was launched at one of our DSL subscribers. This DDoS was large enough to disrupt service to the Redback SMS DSL aggregation router that served this customer and several hundred others. We have blocked the DDoS attack at our edge, thus restoring service to the affected customers.

Starting at about 1:33 PM today, a distributed denial of service attack was launched at one of our DSL subscribers. This DDoS was large enough to disrupt service to the Redback SMS DSL aggregation router that served this customer and several hundred others. We blocked the DDoS attack at our edge within 5 minutes, thus restoring service to the affected customers.

This morning at 11AM, a large DDoS was aimed at a server in our colocation facility in Santa Rosa. The DoS was large enough (1.5 million pps) to disrupt connectivity to our Santa Rosa datacenter, which would have affected access to mail and web services hosted by Sonic. The DoS was blocked by 11:07 AM, and no further ill effects should have been felt after that point.

At 7:17 PM today, a large distributed denial of service attack was aimed at one of our customers. The DDoS attack reached over 1 million pps at our network edge. The primary impact of the DDoS was to destabilize the FRATM/Business-T router that it was aimed at, though all users may have noticed some sluggishness while browsing, due to the impact it had on some of our upstream transit links. The DDoS was blocked at our edge within 10 minutes, and its impact has been mitigated.

At approximately 9:30 PM tonight, an IP in our network was the target of a massive Distributed Denial of Service attack. We were alerted to the attack and blocked it at our edge quickly, but the size of the attack was large enough to congest some of our upstream network connections. This would have resulted in limited or poor connectivity to most Internet sites. This persisted for another 5-10 minutes as we were isolating the affected upstream providers and beginning to contact them to have them block the DoS in their network, however, the DoS stopped before that was necessary.
At this time the network appears normal, and we have taken steps to prevent the DoS target from being attacked again. We apologize for this network interruption.
