Multiple reports of a brief #Starlink outage earlier this morning corroborated by a significant drop in HTTP requests between 04:00-05:00 UTC.

Large burst of #BGP announcements seen at that time as well. Announced IP address space also saw some shifts.

On August 20, Let' s Encrypt switched certificate issuance to use intermediate certificates R12 and R13, retiring the use of R10 and R11. The shift is clearly visible in our Certificate Transparency graphs, starting ~18:00 UTC.

Pakistani backbone provider PTCL is experiencing a near-complete outage, with traffic dropping over 90% around 16:10 UTC.

Interestingly, traffic to Cloudflare's 1.1.1.1 DNS Resolver spiked concurrently with the observed outage.

A nominal Starlink disruption lasted less than 15 minutes, between 17:40-17:55 UTC. Biggest impacts to traffic were observed in the United States, Canada, Mexico, Germany, the United Kingdom, and Nigeria. No word yet on what caused the disruption.

Digital certificates underpin Web security and certificate transparency brings visibility into the millions of certificates issued daily.

Our new Certificate Transparency page shares a wealth of data on certificates, CAs, CT logs, and more.
