So, every night around 7pm, my website home page gets knocked completely off Google. Around 9am the next morning, it returns again. This has been happening every day for the past 7 days or so. After 7pm, not even "site:mywebsite.com" brings up my index.html page. The next morning, everything is back to normal. I suspect Google is testing it's latest algoroithm update, but has anyone else experienced this?
