You might be wondering why we haven't updated outbreak.info for months.
Well, the reason is that GISAID cut our access in January - as they did others. Without telling us.
After a ♾️ back and forth, that is now permanent.
More on that soon - and why GISAID should not be trusted with critical data.

🚀🧬 MY former colleague @micamer.bsky.social who I worked with in the early years of my career has released a BLAST service (GUI + API options) which replicates the NCBI services but with faster response times.
We would love feedback on a new NCBI-BLAST service we are launching today: sky-blast.com
Under the hood it's the same BLAST executable and databases provided by NCBI, with a replica of the NIH's interface - providing an alternative to the US gov service that's less congested, faster & more reliable
