@netblocks Thanks for keeping us posted! I would like to add that the Internet is not down in Iran; but traffic in and out of the country is mostly blocked, excepting indigenous commutation platforms like Eitaa. They still have network service within the country AFAIK. (source: friends who have family there).
Again: if you need to reach loved ones, use a platform like Eitaa and don't use foreign services especially WhatsApp. They are leveraged by the enemy to cause harm.
