Maybe it is the HN Traffic, but I just tried a couple of keyword searches and the site just hangs. It just shows the spinner for minutes on end. I turned off all ad-blockers in case that was the problem, but no dice.

In case it helps the devs, there is this error I see in devtools console: GET https://devslistjules.uk.r.appspot.com/api/jobs?limit=10 net::ERR_SSL_PROTOCOL_ERROR

edited to include console error
