Description Current Status Date Time
This message is a follow-up on the performance issues experienced within ColdFusion 7 on the morning of Wednesday, September 22, 2010. \n\nWe'd like to reassure our customers that we understand what caused the issues and we are changing our procedures to prevent it from happening again in the future.\n\nWe run quarterly Nessus scans in the ColdFusion hosting environment. These scans are part of the regularly scheduled maintenance that has taken place since the introduction of the ColdFusion hosting service at Cornell. \n\nThe issue on Wednesday morning was caused because we have 87 IP addresses on a single server in order to support SSL certificates; because the scan was hitting multiple IPs on a single server, the system was overwhelmed. Once we identified the source of the problem, the scan was shut down within about five minutes, and ColdFusion functionality returned to normal. \n\nThis did not impact our ColdFusion 9 environment, although CF9 instances are also scanned quarterly as a service to our hosting customers.
