Email clicks error

Hello, 


I have some links containing r20.rs6.net in their url that break on some users devices (Android or IOS) 

Some of the responses include

ERR_CONNECTION_TIMED_OUT

Are you doing changes on the r20.rs6.net server or what happens if this work from time to time ?
How I we can be sure users can access links ?

Regards
