Anyone know why etherscan down?
>>>snip<<<
Perhaps someone knows why this happened? Maintenance?
Another suggestion I have for you OP is that you can always check if the site is totally down for everyone or just you.
https://isitdown.me will help you with that. Just type in the domain of the site that isn't loading for you and search. You will get information about the site on whether it's online or offline
Alternatively you can use a multi blockchain explorer like blockchair.com. It can check transactions in the Ethereum network as well.
