When I search for icons, all results appear as broken images. Using browser dev tools I can see all requests to icons.rdl.ink are failing with NS_ERROR_UNKNOWN_HOST. When I try to navigate directly to https://icons.rdl.ink I get DNS_PROBE_FINISHED_NXDOMAIN. Requests to up.raindrop.io work fine. Icons from the built-in list apply fine (but they also appear to be far fewer than I'm used to seeing), but nothing from search results will apply. Is this domain down or has it moved?
