mail.openjdk.org server issues

Hello,
it appears for the past couple of days mail.openjdk.org is having server issues. In nearly all cases the server responds with an HTTP 5xx error. At the moment that seems to be "504 Gateway Time-out", yesterday it was HTTP 500, if I recall correctly.

This only appears to affect some sites of mail.openjdk.org. For example https://mail.openjdk.org/mailman/listinfo is affected, but the mail archives such as https://mail.openjdk.org/pipermail/web-discuss/ don't seem to be affected.

Kind regards
