DDOS of DNS

A distributed denial of service attack (DDOS) occurred (and is still happening) with our DNS provider (Zerigo) -  this caused many users to be unable to look up DNS names (web addresses) - this affected quite a few people. We switched to a DNS server that was not under attack, and then to a new provider. However, changes with DNS take time to propagate (it often depends on your ISP). Services should be returned to normal for most users by now. More posts to follow with details on this and mitigation.
