Data from @CloudflareRadar shows a complete loss of announced IPv4 & v6 space from @FlowStLucia starting at 21:00 UTC, and with it, a complete loss of traffic from the network, impacting connectivity across the island. radar.cloudflare.com/routing/lc?dat… radar.cloudflare.com/traffic/lc?dat…

@reincdr With great power comes great responsibility... :)
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/technologie… #IPv6week2026
A widespread power outage in #Jamaica is impacting #Internet traffic from the island. @CloudflareRadar shows traffic fell ~02:00 UTC, with the largest impact to @FLOWJamaica. The provider acknowledged the issue in a Facebook post. radar.cloudflare.com/traffic/jm?dat… facebook.com/FlowJamaica/po…

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. developers.cloudflare.com/changelog/post…
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
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. facebook.com/SyMOCAIT/posts… google.com/search?q=syria…
@joinraaznet @netblocks @kentikinc @IODA_live @CloudflareRadar Great balanced overview -- thank you for posting. No one organization has a definitive overview of what is happening in these sorts of situations, but a clearer picture emerges when the data is viewed in aggregate.
@DougMadory @mehrdad__ir @Ammir @TheWorld From Iran? No, probably not.
@DougMadory @mehrdad__ir @Ammir @TheWorld Having said that, UDP still accounts for the largest share of requests to 1.1.1.1 from #Iran: radar.cloudflare.com/explorer?dataS…
@DougMadory @mehrdad__ir @Ammir @TheWorld That TLD ranking is based on DNS Magnitude -- see radar.cloudflare.com/tlds?dateRange… for how it's calculated. It would include .ir requests from networks outside the country as well. Over last 48h, largest shares of .ir requests have come from US & DE: radar.cloudflare.com/tlds/ir?dateRa…
Although TXT records still comprise the largest share of requests to @1111Resolver from #Iran, request shares for A and AAAA records have roughly doubled. radar.cloudflare.com/explorer?dataS…
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. radar.cloudflare.com/tlds/ir?dateRa…
🧵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. radar.cloudflare.com/tlds/ir?dateRa…
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. radar.cloudflare.com/traffic/as2765…
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.
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. گفتوگو با نیما اکبرپور، کارشناش فناوری
