i also experience it yesterday after i trade my tokens on etherdelta but it got fix and processed after i a few minutes of refreshing the page . i guess this problem occurs because the etherium network is still congested and heavily traffic due to those cryptokitties that is making the headlines hot recently.
Question. If I sent some ETH, do you think that is affected? I saw a TX page but when I go to double check, get the same "down" error. Thoughts?
affected in the means of what? i sent eth yesterday but it still worked fine after a few minutes of waiting. your transaction will still be safe and okay even if you encounter this error and you will not loose your eth balance.
