[MinistroDolar]

Describe the bug

Seems that our subgraph on Optimism isn't working properly again.

A few users reported that their txns never arrived:

You can also check that there are a lot of incoming txns in the last 2 hours that aren't displayed on connextscan:

The previous fallback strategy was not working, so even though bwarelabs worked at that time, it was just trying to fetch from the hosted-service which was unsynced.
