We did have a brief period of downtime yesterday which affected some of the dictionaries for a bit of time after the server came back up, but kanji is not as extensive of a search, and does not use our dedicated search engine (sphinx).
I cannot say I've heard this happening with anyone else, so if you notice any pattern to it appearing, definitely let me know!
If it happens on desktop as well, and you feel like cracking open the web inspector, I'd love to see what data is being sent by ajax out to the server.
Just got another on desktop when searching for `髪`, which I pasted into the search box. Looking at the network tab, I didn't see a request, even though other normal requests had been sent. Focusing the input and hitting Enter again, did result in a ping to `index.php?page=misc/lookup_kanji` with a valid html response.
It said "No kanji could be found". It is possible the request went out, and the Inspector didn't record it (on Safari) since I opened it after it occurred, but other requests seemed to be there from earlier.
Yea, it had to have gone out - that string is not stored locally anywhere.
When looking at the network inspector, you'll have to check the parameters that were sent with the call, might look something like this (copied from Chrome's inspector - so formatting is a bit off)
