Hi community,

Today is a hard day for all asset-mapper component lovers: the certificate of cdn.jsveliver.net has expired.

Because of that, the command importmap:install fails and deployment can't be done.

I found that there is a solution: calling another endpoint from the ones below:

• fastly.jsdelivr.net
• gcore.jsdelivr.net

Today, two files in the symfony sources contain the string "cdn.jsdelivr.net" (on from asset-mapper component and one from the mime component). They are hardcoded and the only way to override those is to apply a composer patch for example.

Question 1: which solutions could be the best to prevent this issue as best as possible?

Some ideas:

• Configure the other CDNs as fallbacks if the first one fails due to connection error
• Put into a configuration the list of available CDNs

Question 2: is it worth it to implement this logic? Are CDNs just not 100% reliable by definition and we just have to face those issues some day or another ?
