Thanks Eric and Barry.
I was able to surf and connect to other websites, so it wasn't my Broadband.
I was unable to connect to any of my websites (e.g. Bank Genie, Ideas Genie etc) so I now conclude it was indeed the provider.
I reported the 2 problems at 9:32 am and a second one at 9:39 to report that 2 more of our sites were also down.
A few minutes later connections were OK.
Course by the time I have reported and they investigate, its all up and running again and they tell me all is OK.
To keep an eye on this for the next few days, I would appreciate an email if you have connection problems.
