We knew a Google outage had worldwide Internet impact, but do we know just how much? Here’s an unsettling number to chew on over the weekend: the Google outage Thursday that brought down Google’s search platform and many of its Web-based applications meant that 5 percent of Internet traffic went with it.
That’s the statistic offered by Arbor Networks’ Craig Labovitz, who in a Thursday blog post and Web traffic graph noted that between 10:15 a.m. and 12:15 p.m. Eastern Daylight Time, Thursday, average traffic across 10 tier-one and tier-two Internet service providers declined 5 percent.
“If you happen to be Google and your content constitutes up to five percent of all Internet traffic, people notice,” Labovitz wrote. “Network engineers around the world frantically e-mail traceroutes to mailing lists. IRC channels fill with speculation. And end users Twitter (a lot).”

The Web performance research firm Gomez told Business Week that the Google outage also slowed response times for Web sites in 238 of the 560 global regions Gomez covers — a result of the disrupted Google Analytics service and the millions of Web pages that use Google Analytics to track content.
In a statement on Gomez’s website, CTO Imad Mouline outlined the implications of what he described as a “ripple effect.”
