Working fine for me: https://subclipse.github.io/updates/compositeContent.xml

It is just a GitHub Pages site so not much we can do about it being up or down

Tried another machine. It worked there. I suspect this is some sort of conflcit with zscaler

Addressed by adding zscalar proxy as trustyed ca cert for java

https://help.zscaler.com/zia/adding-custom-certificate-application-specific-trust-store

from java root in eclipse:
bin\keytool -import -trustcacerts -alias zscalerRoot -file zscaler.der.cer -keystore lib\security\cacerts
