Alphabet Inc‘s Google has issued an apology for a software upgrade problem that resulted in a significant global outage on Tuesday.

A company representative stated that the team “worked quickly” to fix the issue and that operations were once again normal.

“We’re aware of a software update issue that occurred late this afternoon Pacific Time and briefly affected availability of Google search and Maps,” they said. “We apologize for the inconvenience. We worked to quickly address the issue and our services are now back online.”

Users have been reporting issues with Google Explorer, the most popular search engine in the globe, starting at 2.12 am BST (9.12 pm EST, 11.12 AM AEST), according to a tweet by the real-time website Downdetector.

There were been 4,113 verified reports of Google outages as of 11:38 AM.

Gmail, Google Maps, Google Drive and Google Photos, according to users, are also having issues. Both depend on the search engine Google to function.

Google outages were reportedly affecting at least 1,338 servers worldwide in more than 40 countries, including the United States, Australia, South Africa, Kenya, Israel, parts of South America, Europe, and Asia, according to network intelligence company ThousandEyes Inc. Japan and China.

Before a second blip occurred at about 12 o’clock, the initial disruption noted on ThousandEyes lasted roughly 34 minutes. It took about seven minutes to fix and only affected a small number of servers.

Users encountered a 502 or 500 error when attempting to use the search engine.

“The server encountered a temporary error and could not complete your request,” one error page read.

“Please try again in 30 seconds.”

Users tweeted their confusion and switched to alternative search engines like Bing and DuckDuckGo to browse the web.
