I can assure their PR man that the website has been non-functional all day, constantly, since bang on 8am and it's still inaccessible (as are their phone lines).
Occassionally I can log into my account and try to place an order, just for it to fail. Mostly though it just won't load any pages, or won't let me log in, or dumps me out at a random earlier screen before getting as far as placing an order.
As I type at 3.50pm the message on their website is:
Thank you for visiting the Hargreaves Lansdown Online Service.
Unfortunately this part of the website [the home screen] is temporarily unavailable.
We apologise for any inconvenience this may cause and are working to restore the service as soon as possible.
To place a deal please call us on 0117 980 9800, your usual internet dealing rates will apply.
For any other urgent queries, please call our Online Support team on 0117 980 9953.
Thank you again for visiting."
Their phone lines have of course been engaged solidly all day long.
Good job that trading shares isn't time critical or anything. Who could have predicted that a fair proportion of the (probably) few hundred thousand people they'd bought Royal Mail shares on behalf of would want to sell them. Clowns.
