The Real Bottleneck in Network Incidents Isn't Detection — It's Everything After

Most ops teams I talk to can spot a network anomaly inside a minute. The dashboards light up. PagerDuty fires. Someone acks.

Then nothing useful happens for forty more.

That gap — between detection and actual resolution — is where SLOs go to die, and it's the subject of a webinar making the rounds this week pitching automation and AI-assisted workflows as the fix. The premise is worth taking seriously, even if the marketing wrapper isn't.

In practice, the failure mode here is almost never the alert. It's the human relay race that follows. A NetOps engineer pulls flow logs. Someone else digs through CloudTrail or VPC Flow Logs in one account while the actual blast radius sits in three others. The SRE on call has to figure out whether a BGP flap, a misapplied security group, or an Azure Front Door config push is to blame. Half the conversation happens in a Zoom that nobody is recording.

By the time anyone writes a coherent timeline, the customer impact window is already in the incident review doc.

The pitch for automation in this space usually splits into two camps. One is deterministic runbook execution: when X fires, gather Y artifacts, correlate against recent change tickets, post the summary to the channel before a human even joins. That works. It's been working since before anyone slapped "AI" on it.

The second camp is the LLM-assisted triage layer — feeding telemetry, change logs, and topology into a model and asking it to propose a probable cause. This is where vendor decks get ahead of reality. The models are genuinely useful at summarizing a noisy incident channel or drafting a customer comms update. They are not, today, reliable at root-causing a multi-AZ networking issue without a human keeping them honest. Anyone selling otherwise hasn't sat through a real Sev1.

What actually moves MTTR down, from what I've seen on the SRE side:

• Pre-staged data collection that runs the second an incident is declared, not after someone thinks to ask
• Change-event correlation wired directly into the alert payload, so the first question ("did we just deploy something?") answers itself
• A single source of truth for topology that NetOps and platform teams both trust
• Comms automation that frees the incident commander from copy-pasting status into four channels

None of that is glamorous. None of it requires a frontier model. Most of it is plumbing that teams keep deferring because it doesn't ship features.

One thing the post-mortem will say, every time: we knew within ninety seconds. We resolved in ninety minutes. Fix the middle.

Operational takeaway: if your runbooks still start with "open a bridge," automation isn't your next problem — discipline is.
