No joke here folks. If you are involved in tech I urge you to URGENTLY ESCALATE the news of Symantec SSL/TLS cert distrust.
15 mins of checking in NIghtly and I've found the following are broken:
oyster.tfl.gov.uk
southwesttrains
johnlewis
pcworld
currys
bt
O2
ebay
If these everyday names are not on top of it, your ORG is likely not too.
