Mail Server Outage due to DDoS attack!
It’s likely that at this point you’ve experienced downtime in SmarterMail Server, because of the Distributed Denial of Service (DDoS) attack against our Managed DNS infrastructure this past Thursday, December 22. We’d like to take this opportunity to share additional details and context regarding the attack. At the time of this writing, we are carefully monitoring for any additional attacks. Please note that our investigation regarding root cause continues and will be the topic of future updates. It is worth noting that we are unlikely to share all details of the attack and our mitigation efforts to preserve future defenses.
We also don’t want to get too far into this post without:
1. Acknowledging the tremendous efforts of SATHYA’s operations and support teams in doing battle with what’s likely to be seen as an historic attack.
2. Acknowledging the tremendous support of SATHYA’s customers, many of whom reached out to support our mitigation efforts even as they were impacted. Service to our customers is always our number one priority, and we appreciate their understanding.
Starting at approximately 4.45 P.M, SmarterMail Server began experiencing a DDoS attack. While it’s not uncommon for SATHYA's team to mitigate DDoS attacks, it quickly became clear that this attack was different (more on that later). Approximately three hours later, our team was able to mitigate the attack and restore service to customers. We would like to ensure that enhanced AntiVirus and Firewall are in place and data is safe.
SATHYA’s operations and security teams initiated our mitigation and customer communications process through our support portal. We practice and prepare for scenarios like this on a regular basis, and we work constantly to address scenarios like these.
We appreciate your patience and co-ordination. Thank you for your understanding and continued support!
Thank you and Best Regards,
