Thanks for the report.
Paging @dongbohu. We'll look into this ASAP, collecting debugging info to see why this has happened. And then restart the server. Should be back up by Tues Sep 14 sometime.

The neo4j web server seems working okay now. @dhimmel, did you restart the docker process?

No I didn't do anything. I can confirm that as of ~8 hours ago the problem
existed, but now does not.
Any chance we can get some debugging info from the logs?

@dhimmel: I am in San Diego for DjangoCon now. If you can log into the AWS EC2 instance, feel free to check docker logs. If you can't, I will do it after I am back on Thursday.

org.eclipse.jetty.util.SharedBlockingCallback$BlockerTimeoutException also seems to have been a problem in #9, neo4j/neo4j#9209, neo4j/neo4j#4430.
Perhaps we should upgrade to the latest patch release of Neo4j

You mean Community Edition 3.5.11? https://neo4j.com/download-center/#community

Currently we use:
But there is a 3.2.14-enterprise release, so 6 patch versions ahead of what we're using, each with various changes.
I believe 3.2 is the last Neo4j enterprise versions that are open source. Therefore if we wanted to update to 3.5, we'd have to switch to community. There aren't any major features of enterprise that we use, but sometimes small features get made enterprise. Anyways, lot's of testing will be required to make sure the upgrade doesn't break anything, especially if incrementing major versions or from enterprise to community.
Or perhaps we wait till 4.0 is released and upgrade then.

Sooner or later the support of 3.2.X will be stopped and we'll have to do a major upgrade. If we upgrade from 3.2.X to 4.0 directly, wouldn't it be even more risky?

There's no reason why we have to use a supported version. If an old version works that is not supported, we can use it.
But anyways in #26, I upgrade to 3.5.12. Didn't seem to break anything and it's nice to have the latest features. Perhaps the upgrade will also fix these downtime issues (or introduce new ones 😈).
