If you click on the "track log", you'll see that the aircraft is traveling eastward on every report. The aircraft seems to be traveling about -0.14 longitude per minute at cruise. It looks like a bad report over the ocean at 2230 as it only traveled under 4 degrees of longitude in 50 minute, followed by nearly 7 degree in the following 30 minutes. My guess is a bad report to OAK Oceanic at 2230, which might have created the thick line over the Pacific..

They most definitely did *not* turn around. On eastbound HNL-US flights, the ETP (equal time point) is only about 2 hours outside of HNL. As you can see, at the point in question, it would have been a LOT quicker to just continue onward to the mainland, both in distance and duration, if some in-flight problem had come up.
So yea, it's definitely a FlightAware mistake. The ETOPS equal time point was long passed, and they would have just continued to SFO/OAK/SJC for divert.

FlightAware routinely messes up flight paths on overseas flights. Note the disclaimer on many flights: "At least part of this flight occurs outside of FlightAware's service area. Information on this page may be unreliable."

While FlightAware routinely messes up flight paths outside N. American airspace, this particular glitch is due to Oakland Oceanic ODAPS position report being less precise than those of radar covered areas. I've seen this happening in even weirder ways to Hawaii-Alaska flights.
