Not a general pure image sharing site, but one dedicate for wallpapers (and more) for your personal device (ie your phone), but Zedge did/still provides sharing UGC (user generated content) and as well a premium service for artists.
They are in the margins of positive income at least last I checked.
I noticed a lot of packet loss to 1.1.1.1, not an outright "outage", maybe they were rolling a deployment?
Edit: Looks like a deployment to me (looking at the logs I could see cascading traces, so it took down one DC and the other started responding - increased latency - and then down, etc..), gonna be an interesting post-mortem!
"Update - This afternoon we saw an outage across some parts of our network. It was not as a result of an attack. It appears a router on our global backbone announced bad routes and caused some portions of the network to not be available. We believe we have addressed the root cause and are monitoring systems for stability now.
