answers i know:
She tried Safari, Firefox and chrome
both a Mac and a PC, i don't know what iOS version the Mac is running but i'm pretty sure her PC is on Win7
she says it's been happening for a while now, and she hasn't been able to get on by herself at all.
I don't think so. she says that she can only follow links other people give her but i didn't ask about google. it also affects bookmarks.
every device she owns, plus on other networks.
