Frequently asked

What does "past end of service life" mean?

After a vendor’s last date of support (end of service life / EOSL), the manufacturer no longer issues software fixes, security patches, technical support, or hardware replacement for the product. Each date below links to the vendor’s own end-of-life bulletin.

Can hardware still be used after end of service life?

It can keep running, but it no longer receives vendor security patches or warranty/RMA coverage. Many organizations keep it in production under third-party maintenance while planning a refresh.

How is this list sourced?

Every family listed has at least one SKU group past its vendor-published last date of support. The source bulletin is linked on each family page; where a vendor publishes no EOSL date, EOSL.ai computes it from their published support-life policy and labels it "computed".
