I've got a couple of 1st gen Amazon #Alexa #Echo devices performing excessive #DNS lookups again. None of the other Amazon devices in the house exhibit the same behaviour when using #BBCsounds
They're constantly (every 1.5 seconds or so) looking up "as-hls-uk-live.akamaized.net". It's a CNAME whose A records have a TTL of 20s, and appears to be part of the BBC's streaming infrastructure.
This accounts for ~400 lookups every ten minutes against my pihole, ~90% of which receive cached responses.
