Summary

Media API's instability causes attachment-related features' (such as PDF export) unavailability.

Steps to Reproduce

There's no specific way to reproduce this case because it happens intermittently up to media server's status.

Expected Results

Attachment-related features work stably.
Set up quota per user or tenant to avoid saturation by requests from a certain account if needed.

Actual Results

MediaApiClient faces Media API's errors such as:

org.apache.http.NoHttpResponseException: api-internal.media.atlassian.com:443 failed to respond at org.apache.http.impl.conn.DefaultHttpResponseParser.parseHead(DefaultHttpResponseParser.java:141)

TRANSPORT_ERROR occurs 30k times across 1k tenants per day in the recent 3 days.

With that, MediaApiClient gives up retrying operations 5k times a day among 100+ tenants in total.

Workaround

Wait for a while (say 1-2 hours) and try the failed operation again.
