Lost access on iphone and ipad after changing password on pc?

After changing password, I have now lost all access to my yahoo email from my i-devices. I tried deleting and again adding my account, but have been getting the message: "Yahoo! Server Unavailable Please Try again later". This has been going on for several hours and is very frustrating. Please advise on how to fix this

No one is answering this? I changed my password today too and lost my connection to email in my iphone and ipad! Got the same message - "Server Unavailable".Ps help! SOS!
