3PM June 15th, Google crawling spiked and then stopped completely and traffic from Google was down substantially (95%+) except from Google images which remained the same. Many top pages were simply gone from the index. All returned to normal at 11pm June 15th.
No malware warnings, a complete scan of the source code shows nothing out of the norm, all file last updated dates are accurate.
Perhaps we're all asking the wrong questions? Why is traffic down should be replaced with Where is traffic going since Google isn't experiencing less searches. Knowing where all the traffic sites like even WW lost is going would be eye opening I have no doubt.
