Update: The fault seems to be limited to new deploys, and according to ntomas the problem lies with Heroku Router<p>We just did a routine deploy on Heroku, and _every single request_ began failing. Checking logs it says "code=H10 desc="App crashed"" without anything else.<p>Looking around elsewhere, I see other apps are failing with the exact same error (eg. https://isdown.app/integrations/heroku?c=1685469931)<p>Seems there was scheduled maintenance on some logging system, and there's some homepage / sign-up page service being done too (https://status.heroku.com/).
Sites I've found being down with the exact same error. No clue what's going on here:<p><pre><code> 1. Ours - https://instorier.com
2. IsDown - https://isdown.app
3. LexGo - https://www.lexgo.be
4. Zen Factuur - https://zenfactuur.be/
5. Dandelion events - http://dandelion.events/

Multiple other people on Twitter saying the same: <a href="https://twitter.com/search?q=heroku&src=typed_query&f=live" rel="nofollow">https://twitter.com/search?q=heroku&src=typed_query&f=live</a>
Received a support ticket response saying they are looking into it and that they'd be updating the status page soon. (I want to be understanding, but 2+ hours is a long time to not update the status page)
And now <a href="https://isdown.app/integrations/heroku?c=1685469931" rel="nofollow">https://isdown.app/integrations/heroku?c=1685469931</a> is also down because they use Heroku and they did a deploy without realising they would go offline as a result :-)
Same over here, we're down due to a deploy. Heroku Status green as grass.<p>Edit: Good Twitter thread with some support replies [1]<p><a href="https://twitter.com/nunotomas/status/1663642609527431168" rel="nofollow">https://twitter.com/nunotomas/status/1663642609527431168</a>
Finally there's something on the status page! <a href="https://status.heroku.com/incidents/2554" rel="nofollow">https://status.heroku.com/incidents/2554</a>
