What seems to be the official whatsapp status on twitter is silent: <a href="https://mobile.twitter.com/wa_status" rel="nofollow">https://mobile.twitter.com/wa_status</a><p>Their subtitle "We are working very hard to make this twitter account irrelevant." is quite apropriate if they don't use it (;<p>Just kidding, I love Whatsapp and just saw the talk on Startup School and loved it.
I wonder if WhatsApp's infrastructure is still built on Erlang.<p><a href="https://www.wired.com/2015/09/whatsapp-serves-900-million-users-50-engineers/" rel="nofollow">https://www.wired.com/2015/09/whatsapp-serves-900-million-us...</a>
It is coming back in Brazil, already.<p>Interestingly, their Status Twitter account says "We are working very hard to make this twitter account irrelevant.". As it has not been updated at all today, I'd say they have accomplished it.
