How SREs Can Hit 99.9%+ Uptime With Lightweight Monitoring

Need to hit your SLA targets without drowning in complexity? Pulsey gives SREs real-time, external visibility into outages—no agents or setup headaches required.

Estimated Read Time: 5 min

If your team aims for 99.9% uptime (or better), you know the stakes:

• 99.9% allows ≈ 8.8 hours/year downtime
• 99.99% means ≈ 53 minutes/year
• 99.999% gives just over 5 minutes/year of permitted downtime

Reaching these SLAs isn’t just about infrastructure—it’s about observability.

Visibility First, Then Stability

You can’t fix what you don’t see. External, lightweight monitoring gives you a critical signal before your customers notice.

Pulsey provides that visibility—external uptime logs with minimal overhead.

Built for Quick Response

• 60-second polling of your endpoints
• Tiered confirmation checks to avoid false alerts
• Instant SMS & email notifications, fully configurable
• Agent-free setup—just feed it URLs and go
• 30-day stats retention on the Basic plan (Free includes shorter retention and fewer endpoints) :contentReference[oaicite:3]{index=3}

How SRE Teams Use Pulsey

• Assign alerts only to on-call engineers—no spam
• Monitor production, staging, APIs, CDN separately
• Keep external visibility separate from internal systems

This tool gives you signal without noise—and no configuration headache.

Detect Quiet Issues Before They Get Loud

Downtime is usually silent at first—until support tickets, tweets, DMs, and panic escalate.

Pulsey gives you the early signal so you can fix issues before the noise erupts.
