Scientists sometimes translate radio signals into sound to better understand the signals and they have done so in case of Jupiter. Space sounds are definitely spooky, but a busted speaker would be much more frightening.
But the service is back now and has been restored partially. That means that by the time some users began hearing about the problem, WhatsApp was already working for them again. For a brief period, the particular website faced an outage as well because these sites don't receive so much traffic at once but it spiked all of sudden.
Meanwhile, users took to Twitter to express their outrage over the issue. Other countries where the outage was popping up on social media included Pakistan, Britain, Germany, Brazil, Russia, Vietnam, and Myanmar, Reuters had said. We are working on it and hope to restore the functionality shortly.
