Priority fixes for selectra.info
Ordered by impact and by how common each practice is among peers.
Priority 1 · Harden
Certificate has more than 14 days left
Observed: The certificate from Google Trust Services was due to expire on 2026-11-01 (8 days after the check).
Why it matters: An expired certificate makes browsers show a full-page warning. Renewing well ahead of expiry leaves time to fix a failed renewal.
What to do: Automate renewal with ACME (for example Let's Encrypt or your CDN's managed certificates) and add a renewal review to your release calendar so any certificate inside 21 days of expiry gets attention.
96% of Energy, Electricity & Gas peers do this. Limit: Certificate and protocol were observed from one vantage point; CDNs can present different certificates by region.
Priority 2 · Harden
HSTS kept for at least a year
Observed: Strict-Transport-Security was sent with a max-age of 30 days, below the one-year benchmark.
What to do: Send Strict-Transport-Security on HTTPS responses. Start with a short max-age (for example 300 seconds), confirm every subdomain works over HTTPS, then raise it in steps to 31536000. Add includeSubDomains only when all subdomains are HTTPS. HSTS preload is optional and hard to undo; hstspreload.org itself does not recommend it by default.
On Cloudflare: Enable HSTS under SSL/TLS > Edge Certificates > HTTP Strict Transport Security and raise max-age gradually.
63% of Energy, Electricity & Gas peers do this.
Priority 3 · Harden
security.txt published
Observed: No valid /.well-known/security.txt with a Contact field was returned.
What to do: Publish /.well-known/security.txt with at least Contact and Expires fields, as RFC 9116 requires, and review it before it expires.
On Cloudflare: Cloudflare Security Center can serve a security.txt file for the zone.
7.9% of Energy, Electricity & Gas peers do this.
Priority 4 · Recover
Nameservers spread across providers
Observed: All nameservers for selectra.info belong to Cloudflare.
What to do: Treat this as an advanced step. Add a secondary DNS provider through zone transfers or a multi-provider setup, then test changes carefully, since both providers must stay in sync.
On Cloudflare: Cloudflare supports zone transfers for primary or secondary DNS setups on eligible plans.
17% of Energy, Electricity & Gas peers do this.
