It’s not just you, GitHub is broken. Go touch some grass while you can!

Pathoplexus is growing not only in terms of new sequences, but also integrating into the larger ecosystem of pathogen surveillance by joining WHO's IPSN and expanding membership. This is the way a pathogen sequence database should work! (Lessons learned from GISAID/SARS-CoV-2...)
1/ 🚀 Big thanks to our community - since August we’ve added thousands of new sequences, rolled out major new features, and welcomed fresh faces into the #Pathoplexus world. Let’s dive into what’s new.👇🏻

I want to spell this out in case the implications aren't clear:
This means all public tools/webapps of GISAID data (all the ones you've been used to seeing thru the pandemic, as far as we can tell) are prohibited.
The file allowed this. Cut that - cut off all tools the public & others were using.

On Oct 1, 2025, GISAID informed us that they had ended updates to the flat file of SARS-CoV-2 genomic sequences and associated metadata that we had used to update Nextstrain analyses since Feb 2020. GISAID's stated rationale was that their "resources are limited". 1/5

What an unacceptable impediment to global surveillance of SARS-CoV-2. 👎
