What does your website display now? A 50x server error, or a normal page? If there is a normal page now telling that the website is not functioning and Googlebot is crawling all the URLs it knows, the bot will every time fetch that same page. Because of that the URLs will probably be marked as duplicate content and most of them will become supplemental.

Once pages are marked supplemental in Google, it is almost impossible to get them back as normal again. The speed of this process depends on the crawl frequency on your site. If it is once per month, you are relatively safe, but if your site is crawled weekly or even daily, eight days is a long period as the bots probably already fetched many duplicate "off-line" pages or server errors.

As far as my experience goes, MSN and Yahoo have less problems with duplicate content and you will reappear in those indexes once the old pages are back on-line.

if you have enough links you will survive.
we had that for 3 days last year and it survived.

right now they are just blank html pages. Nothing rendering from php. A few static pages I have work ok.

Why stick with a unprofessional company like this?......My advice would be to move hosts immediately.
