When the gas API is down, the logic we use will no longer compute all of
the data that the gas API returns in order to reduce the burden on
Infura. Specifically, only estimated fees for different priority levels,
as well as the latest base fee, will be available; all other data
points, such as the latest and historical priority fee range and network
stability, will be missing. This commit updates the frontend logic to
account for this lack of data by merely hiding the relevant pieces of
the UI that would otherwise be shown.
When a lot of transactions are occurring on the network, such as during
an NFT drop, it drives gas fees up. When this happens, we want to not
only inform the user about this, but also dissuade them from using a
higher gas fee (as we have proved in testing that high gas fees can
cause bidding wars and exacerbate the situation).
The method for determining whether the network is "busy" is already
handled by GasFeeController, which exposes a `networkCongestion`
property within the gas fee estimate data. If this number exceeds 0.66 —
meaning that the current base fee is above the 66th percentile among the
base fees over the last several days — then we determine that the
network is "busy".
