[Vtigercrm-developers] Marketplace down - causing Slowdown

[Martin Allen]

Glad to hear the new setup is up and running, and from our side we’ve had no more issues with this reported recently so it would all appear to be working !

Hi Martin, Alen,

Apologies for the delayed follow-up — and Martin, thank you for highlighting the issue.

As you mentioned, the delay was caused by the getNews() function in Modules/Users/views/Login.php, which was waiting on an external response that didn’t arrive. The login page only continued once the curl->exec() call timed out, leading to a brief window of 503 errors for new logins. Users already logged in were unaffected.

Over the past few weeks, we investigated the issue, tested application-level adjustments, and finally implemented infrastructure-level caching for a more scalable and reliable solution. We also monitored the changes closely to ensure stability.

Here’s what we put in place:

  *   DNS-layer caching, with tuned TTLs to speed up resolution
  *   Edge caching for the News API (including JSON), so external delays don’t block login
Since making these updates, the system has been performing consistently well, with no recurrence of the 503 errors.

For example : In the last 7 days alone, over 94% of requests — including 16M+ JSON responses from /api/app/news - were served directly from cache. This has greatly reduced backend news API server load and improved response times.

We’d really appreciate it if you could review from your end and share any feedback. Your early report helped us narrow this down quickly — thanks again!

Hi Martin, Alen,

Sorry for the delay, and thanks for your patience! We really appreciate you bringing this up. We've noted the impact of the getNews() function call and are reviewing it internally to explore ways to make the login page more resilient in cases like this.

We're actively looking into this and will follow up with any updates. Thanks again for your insights and for bringing this to our attention!

It was down for about 5 minutes, then went to responding with a 503 response, then came back up normally very shortly after.

Worth looking at the code in Modules/Users/views/Login.php and specifically the getNews() function call.
Basically it was waiting for a response that didn’t come, so only continued when the curl->exec() call timed out.

Anyone already logged in was unaffected - and as all our monitoring is just checking the login page, we had LOTS of alarm bells ringing for a short time!
