The datacentre that hosts my 3 sites has just been down for 57 mins do to a power surge. From a search engine perspective, can i expect serious problems because of this?
Only if you get crawled - and even if you do it's likely only a few of your pages will be crawled rather than the whole site. In my experience, when a site has been down for a few days, it may drop out of the SERPs while the engines can't get to your site - but once the site is back up again it's previous rankings return pretty quickly.
thanks for that, msn and yahoo were on my main site at the time, but 1 hour later they are back on, so shouldnt be too bad. Touch wood.
