Hacker attack

hello everybody,

on monday my website was apparently hacked, somebody requested 15,000 time in the space of a few minutes a file that never existed on my site, the hosting company got suspicious and suspended the site for about 20 hours.
Now this morning I relized I lost a N.2 position I had on google for a few monts now (was in the top 5 for over 2 years) and nowhere to be seen in the top 100
Since googlebot visits the site every day my guess is that it came while the site was down, and since it could not find anything now it took this page out of the index.
Now the site is back up and working, should I expect to get back to my position n.2 soon, or will it take a long time ?
Has anybody else had a similar experience ?
Should I do something or just hope for the best ?
thanks in advance for any advice you can give me

Assuming this was the cause, it should come back as soon as Google re-crawls the page in question. There's never any guarantees that it'll return to the #2 slot, but it should be more or less there.

Google has been playing around with the SERPs quite a bit this month, so your drop may also be related to this.

I'd also start looking around for a better hosting company.

Totally agree, any hosting company worth its salt should be able to deal with a Denial Of Service attack without your site being affected..

certainly you don't want a hosting company that takes you offline for 20hours if someone hits you with only 15,000 requests!

thanks for your replies.
The page in question has been de-indexed by google, the strange thing is that practically all other pages are now back to the original positions, I don´t understand why google would wipe out of the index only 1 page.
I checked the logs and googlebot have been downloading the page in question the last 2 days. Is this a good sign ?
Do you know why if the whole site was down google would take action only on 1 page ?

I would fire that host in a hurry. They are more concerned with saving pennies on their bandwidth than serving your website.

If you make the homepage of slashdot you will get ten times that much traffic.

Now, if you really have been "hacked" they might have placed garbage on one of your pages that downloads a script to your visitors. If google catches you with that stuff on a page they could drop your page.

Check it out.

thanks EGOL.
I checked the code of the page and everything seems normal (can´t find any strange or added code).
What I do have found is that now for the same search I was n.2 at n.4 there is a website about sky holidays (nothing to do with my business) the title of the page is the name of my hosting company, and looking at the source code of the page there is no reason why that page should be there for that search.
What I am about to do is
- check the ibl of this page to see if there is a reason for that position
- check if the site is stored on the same server as my website

Is there something else I should do ?
thanks

I don't know what is going on. However, I am certain that I would get a new host.

as expected there is no reason for that website to be there, the strange thing is the title of the page being the name of the hosting company (this in google, the actual title of the page is different), when the site was suspended if you put my adress you would be taken to a page of the hosting company that said
"this site has been suspended......" I guess they did some type of redirect...I don´t know....anyway I´m looking now for a new hosting.

thanks for the replies.
