kpx.io needs to be updated to April 5th version.
http://kmd.explorer.supernet.org/ is up to date
explorers.supernet.org has a list of all the explorers
if you are running native komodod and have not updated to April 5th version (released last week), you are likely on a fork due to not having the latest version.
The April 5th version should fix the interest rate calculation error in prior version.
This was a planned update and most all the nodes have updated, so the network is running fine, though it seems some GPU pools didnt update so there is much less hashrate, ie slower blocks at times.
