This massive drop reduced available blocks from over 48 million down to just over 737,000 /48s." } }, { "@type": "Question", "name": "What was the immediate impact on total traffic volumes after major providers severed peering sessions?", "acceptedAnswer": { "@type": "Answer", "text": "Traffic volumes fell nearly 90% between 16:30 and 17:00 UTC as major providers disconnected. This rapid decline signaled the transition from partial restriction to a near-total state-sponsored internet shutdown." } }, { "@type": "Question", "name": "How did the share of human-generated IPv6 traffic change before the final disconnection occurred?", "acceptedAnswer": { "@type": "Answer", "text": "The share of human-generated IPv6 traffic dropped significantly from 12% to just 2% during the initial phase. This reduction preceded the final disappearance of IPv6 traffic from the country entirely." } }, { "@type": "Question", "name": "What level of residual traffic remained visible after the internet effectively dropped to zero?", "acceptedAnswer": { "@type": "Answer", "text": "Post-shutdown monitoring showed residual traffic at only 0.01% of normal levels during the blackout. This tiny fraction indicates that only hardened, whitelisted connections survived the infrastructure of silence." } }, { "@type": "Question", "name": "How many citizens were cut off when the regime executed this sophisticated BGP withdrawal strategy?", "acceptedAnswer": { "@type": "Answer", "text": "The January 2026 event successfully cut off 92 million citizens by removing IP blocks from routing tables. This action eliminated the next hop path, rendering addresses unreachable for the vast majority." } } ] } </script> <!-- /wp:html --> <!-- wp:html --> <style> .faq-section { margin: 24px 0; padding: 24px 0; border-top: 2px solid #e5e7eb; } .faq-section-title { color: #1a1a1a; font-size: clamp(1.2rem, 3vw, 1.4rem); font-weight: 700; margin-bottom: 24px; text-align: center; } .faq-item { background: #fff; border: 1px solid #e5e7eb; border-radius: 8px; margin-bottom: 12px; overflow: hidden; transition: all 0.3s ease; } .faq-item:hover { border-color: #2563eb; box-shadow: 0 4px 6px rgba(0,0,0,0.05); transform: translateY(-2px); } .faq-question { background: #f9fafb; padding: 12px 16px; cursor: pointer; position: relative; transition: all 0.3s ease; border: none; width: 100%; text-align: left; font-family: inherit; display: block; } .faq-question:hover { background: #e8f0fe; } .faq-question-text { color: #1a1a1a; font-size: 1rem; font-weight: 600; line-height: 1.5; margin: 0; padding-right: 2rem; display: inline-block; } .faq-answer { max-height: 0; overflow: hidden; transition: max-height 0.4s ease, padding 0.4s ease; padding: 0 16px; } .faq-item.active .faq-answer { max-height: 1000px; padding: 0 16px 16px; } .faq-answer-text { color: #4b5563; font-size: 1rem; line-height: 1.7; margin: 12px 0 0; } </style> <script> (function() { function initFAQ() { var qs = document.querySelectorAll(".faq-question"); for (var i = 0; i < qs.length; i++) { qs[i].addEventListener("click", function() { var item = this.closest(".faq-item"); var wasActive = item.classList.contains("active"); var allItems = document.querySelectorAll(".faq-item"); for (var j = 0; j < allItems.length; j++) { allItems[j].classList.remove("active"); } if (!wasActive) item.classList.add("active"); this.setAttribute("aria-expanded", String(!wasActive)); }); } } if (document.readyState === "loading") { document.addEventListener("DOMContentLoaded", initFAQ); } else { initFAQ(); } })(); </script> <!-- /wp:html --> <!-- wp:paragraph {"className":"std-text"} --> <!-- /wp:paragraph --> <!-- wp:paragraph {"className":"std-text"} --> <p class="std-text">At 11:50 UTC on January 8, Iranian networks withdrew <strong>98.5% of IPv6</strong> address space.

The regime has graduated from blunt force to a mature architecture of selective isolation, executing precise <strong>BGP withdrawal</strong> strategies that dismantle external access while keeping internal infrastructure limping along.</p>
