and I certainly know what that can be like. They seem to have adopted a policy of "plenty of communication that says nothing meaningful is better than no communication at all", and in a way they're right I suppose.
Reasonable and appropriate? Hard to say. On balance I think it's appropriate, but probably unreasonable, given that you say it's an ongoing problem. Can you talk to anyone there? It may not cure the problem they're having, but it might lower your stress level if you knew what it was.
I'm with Blueyonder for a couple of months now and have generally been satified with the service (100k a second download speeds are common) but the email system is a bit "tempremental". I have my email open all day and usually a some point (several times over the course of a day) I won't be able to read it as the server can't be reached. Maybe they just need to boost the number of mail servers as normal surfing remains unaffected.
I have been affected for a few weeks - some days worse than others.(Solihull area)
I have 3 mail boxes - sometimes like today all three have problems - sometimes it is only one or two of them.
Two weeks ago one of my addresses would not connect for two days - blueyonder helpline tried to correct the problem but then concluded that my mailboxes were possibly on different servers and a particular server was playing up. It corrected itself on the third day.
