RESOLUTION - 9:42 AM ET - All systems are back up and running as expected. The issue this morning was caused by a DDoS attack. We have successfully contained the issue and will continue to monitor the situation.
A Distributed Denial of Service (DDoS) attack is an attempt to make an online service unavailable by overwhelming it with traffic from multiple sources. They target a wide variety of important resources, from banks to news websites, and present a major challenge to making sure people can publish and access important information. Unfortunately, these attacks have become common with more than 2000 daily DDoS attacks world-wide and over 1/3 of all downtime incidents are attributed to DDoS attacks. For more information about DDoS attacks, please refer to http://www.digitalattackmap.com/.
9:39 AM ET - We are seeing intermittent "Service Unavailable" messages on job boards and resources subdomains. Please be assured that we are aware of the issue and we are working on finding a resolution to the problem.
We will continue to provide updates here as they become available.
Our sincere apologies for any inconvenience it has caused.
