Dec 5 (Reuters) - Cloudflare has restored impacted software services after a minor outage on Friday hampered access to crypto trading exchange Coinbase and Anthropic's artificial intelligence chatbot Claude AI.

The web-infrastructure company's shares fell as much as 4.5% in premarket trading, as the disruption came less than a month after a widespread outage prevented thousands from accessing major internet platforms, including X and ChatGPT.
