If you guys are not aware or are seeing traffic drop in your site which is hosted on blogger.com, then you all should know that even blogs hosted on Google-Blogger server wents down for few seconds many a times in whole day. I am monitoring my blogs from last few days and every day i am bombarded with website down emails. You'll be amazed when you'll also get those emails. And it will not matter whether your using the default domain with blogspot.com or .in or having a custom domain. The situation is same for every case.
And to monitor the website, there is a very nice tutorial written on Labnol by Amit Sir which pings your website every minute (using google docs) and the time you site goes down, it sends you an email telling you when its up or down. Follow the instruction to monitor site here - http://www.labnol.org/internet/website-uptime-monitor/21060/ and set the ping time to one minute.
You can even use pingdom too, make a free account on it and add your site for monitoring. It offers to add one website only in free account. But its worth using it.
And do let me know too whether you're also seeing your site going down or not? And thanks to Shubham for making me aware about this problem.
