Any issues going on with steem coins at various exchanges now?

I have been trying to trade my steem coins in Poloniex exchange and I see this banner below from last week.

I submitted a support ticket to Poloniex but no response so far.
Then I tried to see if I can trade steem coins in blocktrades.us and I see another banner.

I tried to look in reddit forums and steem website to get any information on the steem outage. Does anyone know if there is a serious issue/outage with steem going on now?
