I have 3 ESP8266 chips that I use as water alarms and one a doubling as a pool furnace controller. They have worked for 4 months then now they all went dead. When I connected one to my computer it just kept attempting to connect to cloud.blynk.com 8442 and never did, please help someone! 
there’s a few existing “please help me!” threads
the server went down and you need to reboot everything…
I have rebooted everything but that isn’t working
it’s not working for me yet either 
OK well thanks now I know it’s not just me
