Support Runway Score

Every tracked Juniper M/MX Series M40 SKU group is past Juniper end of service life (last group Jan 2016). Units in production should be treated as unsupported. For past-EOSL units, weigh third-party maintenance, spares, replacement, or a documented run-to-failure.

Options from here

Unsupported now

The Juniper M/MX Series M40 is past Juniper end of service life. These are the paths teams take from here:

Third-party maintenance

Keep it in production past the OEM cutoff with an independent maintainer.

Pre-stock spares

Buy spares now, while units still circulate on the secondary market.

Plan replacement

It is unsupported today — set a migration timeline and budget.

Run to failure

Low-criticality role — document the risk, harden backups, retire on your terms.

Independent and informational — EOSL.ai sells no hardware or maintenance and lists no paid placements. Third-party maintenance keeps unsupported gear in production past the OEM cutoff; whether it fits depends on the asset's role.
