There were reports regarding the possibility of restricting internal access between users and some datacenters by the Islamic Regime in order to prevent l2tp/wg/ovpn tunnels through the Iranian Starlink owners / whitelisted servers and normal users who have restricted internet access.

Quoted tweet from @netblocks:
⚠️ Confirmed: Metrics indicate a collapse in connectivity on AS12880, a key #Iran telecoms network that had so far remained partly online as part of the ~1% reserved state infrastructure. The incident corroborates reports of instability on the NIN domestic intranet.
