If a large enough coronal mass ejection (CME) from the sun delivered a strong electromagnetic pulse (EMP) through the Earth, they'd both cease to exist. Pretty much instantly. But there'd also be no more electricity, so it'd be a frantic effort to figure out what happened to them. Actually, only employees and their families, and stock holders will be wondering what happened to Google. Everybody (except perhaps a small area in and around Pennsylvania) will be wondering what happened to the electricity.
Ironically, that would be a highly interesting technical event to post to Hacker News if it happened... and it actually could.
