I've been using Blekko more frequently in various subject areas, and digging deeper into their results pages. During the past three days, during some intense and lengthy results browsing, I received a page display titled "Blekko: too much traffic". The message text reads: "we're sorry... We're getting more traffic than we can handle right now. Take a break and have a cup of coffee while we catch our breath. Please try again later. If you believe you have reached this page in error, contact us at ..." This occurred a minimum of three times during each search session, and there were several search sessions, at various times, each day. Has anyone else experienced this? Are their servers that busy? Something else?
