    Traffic levels into Iran have reached 60% of pre-Jan 8th levels as the partial internet restoration continues to unfold. Iran may be entering a phase that resembles the partial restoration (Jan 27 to Feb 28), marked by instability and erratic blockages. #DigitalBlackOutIran‌

    Large BGP routing leak by a provider in Russian-held Luhansk, Ukraine. From Kentik's perspective, 91% of misdirected traffic was bound to Russia and Russian-held Ukraine.

    Taking a look at this BGP hijack of 162.55.80.0/24 that targeted Virtualizor in recent days. Hijackers forged the origin to make the route RPKI-valid: ... 6204 62390 24940 (hijack AS path) ... 24940 (legit AS path)

    Latest chart for traffic to Iran since December 2025. We saw steady growth between the partial restoration of May-26 and Aug-1, followed by new instability in traffic levels. Still a long way from pre-Jan-8 traffic volume levels. #DigitalBlackOutIran

    These leased IP ranges originated by Canadian telecom Rogers (AS812) belong to Ukrtelecom, had their registration changed to "Rogers Communications" and, of course, are full of proxies. bgp.tools/as/812#prefixes Part of the Exodus of IPv4 from Ukraine: kentik.com/blog/exodus-of…
