Thanks for the info.

As for outages, there have been multiple outages before this one. Sometimes an outage situation went like this: Regarding account history API calls, some API nodes still worked correctly but others not. After api.steemit.com came back, those previously problematic API nodes worked correctly. That's why I think STEEM API nodes are not decentralized enough.

Considering that running an independent full API node is not a small task, I think it would be better if there is one more official API node from Steemit Team.
