Impact of DNS Error on Google ranking

[aspdaddy]

A fairly big UK hosting reseller has been down most of the day because of an ISP outage inLondon. I have a load of brochureware sites on it what do you think the impact on Google rankings will be? All servers are responding with the Cannot find server or DNS Error.

These sites only get a few dozen users a day from Goggle searches, not reliant on it for busiess etc but the log and search data generated is valuable, would be a pain to lose them from the G index.

How long before sites are dropped for this . and will they re-crawled by googlebot when its back up?

This happened to me earlier in the year so I unless things have changed in the last 4 months (and it's a possibility) I can teel you what happened.

My sites were unavailable for just over 24 hours and we were worried about what would happen when the bots couldn't find the site.

I'm pleased to say that once the site came back the bots came round again as normal and the positions did not seem to change (well, by 1 or 2 but that's normal for the phrases that we monitor - one phrase we check seems to vary between positions 2 and 4 on a 421 million results search on Google.Com.

Mind you, if the bots had come back 3 or 4 times and not found the sites I suspect that this would have affected the rankings (but this is only a gut feeling).

It happened something similar to me: it's a disaster.
Can't predict exactly what will happen but it's not good. Perhaps you will have your site available and ok if it's short time (weeks?). To me, spoiled my ranking, later had to move from hosting company. Took me months to recover the Google rankings I used to have, but the hosting company was a real nightmare and yes can hurt your Google positions indeed.
In my case once the site worked, they forced me to take a higher plan (of course more expensive) The company was Micfo which I don't recommend to anybody.

Beware of bad hosting companys, it's better to move on than loose your business.
Bot's will come back, but perhaps you may want to move to another hosting company and keep your old site there while is crawled and indexed again. Then drop the problematic one.
