My seed node at steem.global:2001 is operational. Hopefully more continue to run for witness and start up seed nodes as well.
it should be nearly mandatory that a witness runs a seed node in my opinion. We're here acting as server jockeys for the network and it's not terribly difficult nor expensive to set up a seed node.
Is yours in seednodes.txt? If not, please send a PR.
Looks like it is on line 24 on the seednodes.txt seen here:
https://github.com/steemit/steem/blob/master/doc/seednodes.txt
Is there a reason for it currently not being obligatory?
