I got an email the other day about them migrating over to their new upgraded email service some day this week. It could have been today and you were trying to access it during the migration. I just checked mine and I can get in as normal. Probably just timing!
Hi, Yes,. I've had endless problems with eircom.net emails. Dont think I will bother much with them anymore and will use an alternative as it's too much trouble now.
