Internet in Iran is still only partially restored following the end of the 88-day shutdown on May 26, at most 60% of pre Jan 8th levels measured in bits/sec.
Traffic volumes into Iran were stable over the weekend despite recent airstrikes. #DigitalBlackOutIran

6 June is the anniversary of the #WorldIPv6Launch.
Since 2012, IPv6 adoption has increased from 1% to 44% globally, and is exceeding 50% in the Americas and the Asia Pacific region. pulse.internetsociety.org/en… #IPv6week2026

Radar traffic charts now default to daily granularity for 1-3 month ranges and weekly views for longer durations. Get way more data points to analyze trends.

Glad to see this -- makes long-term data so much more useful.
📢 New feature alert! Radar now supports finer-grained chart granularity for longer time ranges. This means:
✅ 1-3 month views: weekly → daily (7x more data points)
✅ 6 month HTTP views: monthly → weekly (4x more data points)
💡A 12-week traffic view used to show 13 weekly data points — now you get 90 daily

In a Facebook post, Syria's Ministry of Communications & Information Technology announced that there will be no communication cuts during the general exams this year, in contrast to #Internet shutdowns implemented in past years.

🧵Some additional perspectives on the (limited) restoration of #Internet connectivity in #Iran on May 26:
Based on request traffic to @1111Resolver, the rank of the .ir ccTLD has jumped from #144 on May 25 to #96 on May 28.

Digital certificate issuance volume for .ir domains briefly jumped from <1,000/hour to >4,000/hour, suggesting manual & automated renewals from within the country were once again possible. Nearly all were from @letsencrypt.

Although TXT records still comprise the largest share of requests to @1111Resolver from #Iran, request shares for A and AAAA records have roughly doubled.

This cable damage has taken @DigicelHT completely offline, as @CloudflareRadar shows that #Internet traffic and announced IP address space all dropped to zero just after 22:00 UTC (18:00 local). Similar problems occurred multiple times in 2025.

Nap enfòme kliyantèl nou a, ke aswè a @DigicelHT sibi de koupi adisyonèl sou 2 lyen fib optik entènasyonal li yo nan sòti PauP sou wout nasyonal 1. Sèvis entènèt, SMS, Moncash ak apèl entènasyonal. Ekip nou deplwaye, e nap evalye aksè yo pou fè reparasyon pi rapif ke posib.

Cloudflare Radar data confirms early indications of a partial Internet restoration in Iran, nearly three months after the shutdown began. Traffic spikes and DNS queries have risen, but network activity is currently just 40% of pre-shutdown levels. cfl.re/3S675CL

از رسانهها و فعالان خواهش میکنم که نتبلاکس رو مرجع قرار ندن. نتبلاکس در سنجش وضعیت اینترنت در ایران دقیق عمل نمیکند. متریکهای عمومی نتبلاکس برای شرایط اینترنت در ایران کافی نیستند.
سطح دسترسی به اینترنت حتی نزدیک به عددی که نتبلاکس اعلام کرده هم نیست.
رادار کلادفلر، IODA و گزارشهای @DougMadory بهترین مراجع برای بررسی سطح دسترسی در ایران هستند.
May 27
نتبلاکس اعلام کرد با اتصال دوباره شبکههای موبایل و بخشی از شبکهها به اینترنت جهانی، سطح دسترسی به اینترنت در ایران به ۸۶ درصد رسیده است. با این حال کاربران همچنان از محدودیت در اینترنت خبر میدهند.

We are still in an internet shutdown. Traffic exists, but it remains far below pre-Dec/Jan levels, with about a 50% drop in national traffic since then. We need to see whether it returns to previous levels or stabilizes at this new low. Don’t rush to conclusions.

Just to keep today's partial restoration of Iranian internet connectivity in perspective, please take a look at this overall timeline.
Iran has a long way to go to get back to pre-Jan-8 levels of traffic volumes. #DigitalBlackOutIran
Seeing the first signs of a possible internet restoration in Iran at 12:01 UTC today.
While a few networks spiked in traffic, most are still down.

Exam season in #Iraq started today, and with it, widespread #Internet shutdowns. Connectivity was cut across multiple major ISPs between 0300-0430 UTC, though networks in the Kurdistan Region remained available.

The shutdowns in Iraq are implemented by having network providers withdraw announced IPv4 and/or IPv6 address space, effectively removing them from the Internet.

New on Cloudflare Radar: MRT Explorer!
BGP is how networks tell each other where to send Internet traffic. MRT files record those routing updates, helping investigate outages and route leaks.
Now you can inspect them directly in your browser:

I was one of the 1100 impacted by yesterday's layoff at @cloudflare. Thankful that I had the opportunity to work on @CloudflareRadar over the past 4 years, evolving it into a trusted industry resource. Would love to continue working with #Internet data in my next role...
