Cloud Computing Dangers: A Case of the Mondays

This posting is Part 8 of the Case Study in Cloud Computing Dangers.

We started the business day on May 14, 2012 finally able to send email to the primary contractor on our VA project, but not to the VA email accounts. This development was not an indication that Day 5 represented the end of our outgoing mail Denial-of-Service between our Office 365 cloud service and just about any mail gateway using Cisco devices or any other devices that used senderbase.org to receive SPAM reputation scoring. The organization had simply been shamed (either within or without) into lowering its SPAM blocking threshold to allow any email through that was rated Neutral. Not only was the organization the victim of being unable to receive legitimate email from business partners and clients, it was forced into a making a business decision that would allow more malicious messages to pass through the gateway. It was not a good sign.
