Ok I have made a blog using blogger a few weeks back, all the content has been written by me (its not copied), the posts are nearly about 300-400 words, it was all going well but there was a problem which i have absolutely no idea about

When i was opening the blog from two random locations at the same time it was showing an error of 404 page not found!!
Can someone tell me why is that??? Now when I login into my blog it's working fine. I want to know why did that happened??? Since I haven't practiced any black hat technique till now.

Thanks in advance

Got nothing to do with 'blackhat' or otherwise, just a server error more than likely.
If it works fine now dont worry about it.
