I know there are more posts about this - but I’ve never encountered this before. I have a paid (pro) account and I suddenly noticed last week or so that my site was slower than usual. So checking the trace, I found that I was connecting to the LHR colo. This is not a normal situation - I ALWAYS used to connect to AMS (which really is a lot faster for my location).
So the question is; why am I now suddenly connecting to LHR? It has been like that for at least a week now… I checked the status page but AMS seems healthy.
The site in question is a CF Worker Site that gets it’s resources from a KV store. Not sure if that information is useful, but it might?
I realise that - however, we always (and I’m talking years here) where connecting to AMS. I also did a test (webpagetest.org) from a datacenter I know actually resides in an AMS DC - and that one still connects to LHR.
The difference between LHR and AMS is about 100 - 200ms (total load time homepage)… Ping time difference is 20ms (for 18.104.22.168) and 30ms (to the site). Slower is relative, however, we’ve spend a huge amount of effort in performance and it’s a shame that (suddenly?) CF decides to route to a less than ideal colo costing us precious ms…
The real issue here is - why is it suddenly doing this…?
