https://unpkg.com/ appears to be experiencing some instability and unreliability right now. This is an <excellent> opportunity to identify any assets that you're not caching and/or are directly pulling from unpkg.com in your production environment.<p>I've encountered "HTTP 520 Web server is returning an unknown error" responses intermittently from Cloudflare.<p>Recurring downtime for unpkg.com has been an issue in the past. In August 2022, Shopify notified its partners to switch from unpkg.com to jsdelivr.net [1]. I can only speculate that Shopify made this recommendation due to the negative impact of unpkg.com's downtime on numerous online shops.<p>[1]: jsdelivr.net offers a convenient tool for this migration at https://www.jsdelivr.com/unpkg.
