How long can a site be offline without Google trouble?

we have taken our server offline, how will this affect serps?

I have made the decision to take our server offline for 2 days due to personal reasons. My question is will i lose my PR in these two days? Will my site be dropped from the index, or lose its rankings in Google? How long (days) can a site survive being offline before Google recongizes this and either removes it from the index, drops pr, or loses its rank? Is anyone familiar with a timeline?

There was an interesting post on Matt Cutts [ Google Employee ] blog that talked about 404 and 410's.
You might want to look that over and ask that same question to him.
I am sure many of us would like know that bit of information.

The server is currently unplugged for this period of time, and I'm trying to make the decision to turn it back on IF there will be harmful reprecussions from Google during this 2 day blackout period... Also as a result i cannot setup 404 or 401s i assume.

Things may have changed but in the past being down a couple of days didn't hurt at all.

Last fall, WebmasterWorld was offline for one full and disastrous week, but there was no obvious effect in Google from that event.

Thats what i assumed as well. Just wanted to double check however as google may have changed how they handle outages recently. Anyone else ever had a immediate negative impact for a few day outage in regards to your visibility in google?

It seems that Google is extremely tolerant of websites being offline, and keeps attempting to spider them. I guess it may give up after a long period of inactivety though.

My site was offline recently for 6 hours whilst we upgraded the server, and as soon as it returned, Google was spidering.

A site of mine was down completely for 8 days after a DDOS attack. It stayed in the serps throughout the 8 days and only slipped 2 places by the time the site was back up and running (on the same host/IP).

Two weeks of the server seding a 404 for all pages (that's not the same as "server not responding" that you have done) is enough to get Google to drop all the pages from their index (as long as the pages are NOT supplemental results - those it keeps for two years, or more).

hehe, not sure if this makes you feel better...

One of our sites was taken offline by the clueless host and put a 500 error msg up. Was offline maybe 48hrs. Switched hosts. Appears we lost 10-20 positions for our top KW. Looking for a rebound asap :-)
