My faith in Fastly was shaken after earlier this year, we experienced connections intermittently failed (HTTP 5xx) to any service behind Fastly (ours and third party) in our Amsterdam datacentre. We contacted their support but told us repeatedly it must be our fault (like a proxy). Long story short after investigation it was confirmed to be their fault and most likely a machine-gone-bad in their PoP and the intermittent nature was related to balancing across them. This was not resolved until their team woke up and we pinged their team on IRC. It shook my support from the obvious lack of monitoring or on-call system.
