• Diversifying infrastructure and using multiple providers can help mitigate the impact of outages.
• Some users were able to bypass Cloudflare's issues by using their API or changing DNS configurations.
• The inability to disable Cloudflare's proxying during the outage was a significant issue for some users.
• Using a short TTL can help reduce the impact of DNS changes during outages.
