kensium (1994550) writes "It is sometimes argued if a site's visibility in Google's search results can be influenced in a negative way if it's unavailable when Googlebot tries to crawl it. Sometimes downtime is unavoidable: a webmaster might take a site down due to ongoing site maintenance, or legal or cultural requirements. Outages that are marked ambiguously can negatively affect a site's reputation. While we cannot guarantee any crawling, indexing or ranking, we can devise ways to deal with planned website downtime in such a way that would generally not negatively affect your site's visibility in the search results."
