@ashih - Thanks for the report - can you give us the full request with headers and the responses as well (especially when you get a 404). It may be our Cloudflare CDN

from openjdk-api-v3.

I wasn't able to repro the 404 recently, but the http headers look like the following for a 200 take from yesterday:

If it helps you to track it down, we saw many errors on June 4th, 2020. I'll bring up more instances when they come up. Is there a way to grep server logs for a request for the URL https://api.adoptopenjdk.net/v3/assets/feature_releases/11/ga?architecture=x64&heap_size=normal&image_type=jdk&jvm_impl=hotspot&os=linux&page=0&page_size=1&project=jdk&sort_order=DESC&vendor=adoptopenjdk for 404s?

Today we saw a 200 with an "Application is not available" result. Please see the text below:

Hi any update on this?

from openjdk-api-v3.

johnoliver avatar johnoliver commented on September 14, 2024

Out of interest, are you seeing any 404s recently? We did roll out some updates that may have improved the situation. We have external monitoring running and it has not recorded any downtime of the api in some time.

We are seeing 500s and 503s instead of 404s now: one on 6/10, one on 7/20, 4 on 7/29 and 7/31, 3 on 8/5
