The JP node has been losing network connection on and off over the last few hours.
The provider says there's a DDoS going at their servers.
The most annoying part about it is that I'm in Tokyo and still losing connection directly to it/can't connect to it.
As usual, you should have a backup to one of the other nodes - and from Japan that would probably be best to use stratum.kano.is as the backup.
They seem to think it is now resolved - and the last disconnect message I got was about 20mins ago so hopefully all OK again now at the JP node.
This is going on again today also
They said they fixed it again today but then it started yet again.
As before for the few people that mine on the JP node, be sure you have that backup setup.
This was FINALLY sorted out at 02:28 UTC
JP node been OK since then.
On another note though, the nonce server got rebooted by that (different) provider (with no warning) and I mistook the alerts being more from the JP server.
Sorry about that.
The nonce server was down from 02:32 UTC til 03:24 UTC but back up and running all OK again.
Edit: and just as I posted this ... the JP node dropped it's connections again
So it WAS working for 1.5 hrs but yet again the network at the JP node is playing up.
