Yes, that IP is blocked at our firewall, and has been since July 9th. So this isn’t a routing problem, and it isn’t new. I no longer have the logs from when it was added, so before I lift it I’d like to understand what the integration does so it doesn’t end up blocked again. Can you share which endpoints you call, how often each account syncs, and what the client does when a request fails or times out? Twenty accounts behind one IP is fine, but the combined rate should stay under roughly 100 requests a minute and failures need to back off instead of retrying right away. Once I have that I’ll remove the block.
