Service unstable?

Hi @alanshaw! I just found that I keep getting error like Internal Server Error on https://david-dm.org, and the image/badge is also unavailable. Is there anything I can help? Thanks!

@alanshaw I think the consensus feeling here is not that we’re frustrated by your lack of time to work on this. Really want to emphasize – even overemphasize if possible – how thankful we are that you do any of this at all.

Rather, I think we’d just love to see what’s frustrating you or blocking you right now, raw and out in the open. That way we can help to share the load. It ain’t heavy if we help!

I have very limited time to work on david outside of my day job and I’m trying to work on this whenever I can so please be patient.

I believe the most recent downtime was that the david module was upgraded to use npm@4.x whereas the website was still using npm@3.x. I’ve now updated the website so they’re both using the same version. Hopefully that’ll help.

The wider issue is that the site is popular, and doing a lot of work on every request. It depends on two external services (github+npm) that sometimes respond slowly to requests. Many requests to david and slow responses from github and/or npm causes a backlog that is difficult for it to clear, causing it to be unable to respond to requests in a reasonable time. The two need to be decoupled so that david can respond quickly to requests, and update dependency information in the background. I’m working to address this.
