Google's Australian services were hobbled briefly last night, most likely due to a power outage at one of the Sydney data centres where the internet giant has peering points.
Internet users with the likes of Optus, Internode and iiNet took to the Whirlpool forums and Twitter at about 8.25pm AEST Wednesday, reporting either slow or no access to key Google services.
Several produced trace routes that initially showed Google timing out, before traffic was rerouted via locations in Asia and the United States.
A Google spokesman could not confirm the cause of Google Australia's accessibility issues at the time of publication.
However, Google is known to have a handful of racks of gear, mostly for peering purposes, housed within PIPE Networks' PPC-1 cable landing facility in Sydney's northern suburbs.
The facility is also home to servers from Victorian hosting firm VentraIP, which also suffered problems during the cable landing station power outage last night.
VentraIP reported that it lost power to the PPC-1 data centre, "as did another big client you probably know of by now".
It refused to disclose the identity of that client, though when quizzed if it were Google, noted: "If they're down at the moment too, who knows?"
iiNet representative David Harmsworth confirmed that problems reaching Google's Australian web properties appeared to be on the web giant's end.
"We have our own Google caches that we host within our network – these are running and serving some traffic, but are down on traffic compared to normal for some reason," Harmsworth noted.
"Checking out other graphs at my disposal, it appears that Google themselves aren't sending much traffic out their peering points in NSW."
Mains power was restored to the PPC-1 facility at about 9pm, according to an issue advisory by VentraIP.
However, VentraIP noted its servers were not protected by uninterruptible power supplies (UPS) immediately following the incident. That issue was resolved just before midnight.
Access to a post-incident report from PIPE has been sought by CRN sister site iTnews.
It was unclear at the time of publication whether Google Australia had reinstated traffic through its NSW peering points, or was continuing to divert to offshore.
