Since June 27th, any CI job running 'npm install' might suffer from a 10<br>
minutes extra delay.<br>
<br>
Somehow when requesting package informations from the NpmJS CDN<br>
(CloudFlare), the connection holds for ten minutes. npm just idles<br>
waiting for a reply. Then eventually it shows:<br>
<br>
npm ERR! registry error parsing json<br>
<br>
npm then retry and process as usual.<br>
<br>
<br>
The json error is due to a CloudFlare HTML page stating:<br>
<br>
The page could not be rendered due to a temporary fault.<br>
<br>
<br>
The impact is any Jenkins job using npm have a high chance of taking 10<br>
more minutes to build. That notably impacts MediaWiki core and all its<br>
extensions.<br>
<br>
<br>
A few minutes ago, I have made a change to run npm with --loglevel=info<br>
which would give some hints about what it is doing by causing npm to<br>
emit more informations in the console. (verbose would be way too much<br>
log though).<br>
<br>
I have filled a bug to npm: <a href="https://github.com/npm/npm/issues/21101" rel="noreferrer" target="_blank">https://github.com/npm/npm/issues/21101</a><br>
Our task: <a href="https://phabricator.wikimedia.org/T198348" rel="noreferrer" target="_blank">https://phabricator.wikimedia.org/T198348</a><br>
<br>
<br>
I have no idea how to mitigate the issue :-(<br>
