Update at 23:11 pm: Still no improvement in the disorder.
Update at 21:12 pm: The suspicion about the DNS problem seems to be confirmed. Experts also agree:
Facebook, Instagram, WhatsApp are all down, because it appears their whole BGP table got withdrawn from the internet. Because they host their own DNS servers, and those routes have disappeared, they can't bring the routers back up because they can't get into them remotely. 1/
