All,
Effective last Friday (24th April) the issue is apparently resolved. My own testing seems to confirm that, though I was unable to get any details from the Akamai NOC as to the cause of the underlying issue. Hopefully that's the end of it, but this has reoccurred before, so will try and keep tabs on it.
Cheers,
-SDL
