"AI, he said, is fantastic for the observation part. 'It reads the logs at the speed of I/O, it doesn't get bored, this at scale is something no human can match.' He recounts a real incident when, on New Year's Eve, Claude Opus 4.5 was returning HTTP 500 errors. 'I open Claude Code and ask it to have a look.' The AI wrote a SQL query and 'within seconds it has the answer, an unhandled excep'"
"It would be hypocritical to say that Claude fixes everything. My team exists, we're hiring for many positions, this should show you that no, it doesn't work. However, he said many of us would not be surprised if it did work in future, and his talk demonstrated that AI is already helpful."
"Speaking of his career in incident response, Palcuie reflected that having engineers on call is a tax on humans because our systems are not good enough to look after themselves. Your phone buzzes, there's half a second where you go from asleep, to incident commander mode... then at 9:00 am you show up at work and have to look professional and presentable."
Anthropic's Alex Palcuie, formerly a Google Cloud Platform SRE, discussed Claude's role in incident response at QCon London. While Claude excels at rapid log analysis and observation—processing data at I/O speeds without fatigue—it remains a poor substitute for human SREs. Claude frequently mistakes correlation for causation and makes critical errors in decision-making and action phases. Palcuie's team continues hiring despite using Claude for incident response, indicating the AI cannot fully automate SRE work. However, he acknowledged that future improvements might change this. Incident response involves four phases: observe, orient, decide, and act. Claude performs exceptionally in observation but struggles with the reasoning required for effective incident resolution.
