I have a website which is ~7 month old
Nothing special, not blackhat techniques. Just a small blog and around 30 back links. Amount of posts and pages ~ 70. All manually written, all original.

Everything was fine till begin on September
At that time the following happen:
1) Problems on hoster side made robots.txt unreachable for 2-3 days
2) I added 5 outbound links to sponsor sites
3) new google panda update?
And now I see how my 10 000 impressions in search results are becoming zero.
I wonder can it be explained by the reasons above?
