Is there such a beast? If we can't find one, we are most probably going to self-host Sentry - has anyone had any issues with it?

Are you using anything else?

Below is a list of the ones, that are excluded based on my research (and may be helpful for someone else):

NewRelic - hosted in the US, Chicago, Server Central [1]

Datadog - hosted in the US, "primarly Virginia", AWS [2]

Rollbar - hosted in the US, Iowa [3]

Sentry - hosted in the US (answer from support)

Waiting for support answers from Airbrake and Raygun, will add them later.
