It may be coincidental but I've also noticed unusually long delays sending email via my iCloud account for the past couple of days. Watching the Activity Window it often displays this for a good minute or more:
Followed by this error message:
When I click on "Try With Selected Server" the email sends instantly. The Connection Doctor shows an immediate, "green light" connection with iCloud too.
The problems seem to be intermittent...sometimes a web page hangs in Safari other times the same web page opens instantly (with the history/cache cleared or not). The "hangs" are also intermittent with my iCloud email service.
Using Firefox or Chrome the same websites load immediately. Using one of my other (non Apple) email addresses, all emails send immediately as well.
One of the worst "offenders" is this very website (Apple Support). Sometimes I have to reload it three or four times to get to it in Safari, yet it loads normally using other browsers.
Wonder if this is connected to an issue Apple had (or is having) with their servers noted here yesterday: http://appleinsider.com/articles/15/03/25/yet-another-outage-hits-apples-app-sto re-itunes-preventing-searches-discovery-downloads
BTW, I'm located in the Pacific NW.
Hoping this gets resolved sooner than later...very frustrating.
