Based on the traffic we observed in Iran, it appears that TCI has started implementing domain whitelisting on their DNS servers.
This might be a configuration mistake, but according to our logs, since this morning most domains have been resolving to the internal IP 10.10.34.35.
Some of the most frequently used domains were occasionally corrected, but many services such as bale.ai, zarebin.ir, and several others have still not been fixed.

Updated: every thing got normal in later check.
