Yesterday we identified and fixed an issue in Bristol which we believe may have been causing corruption or delay to HTTPS packets. Would you be able to test this evening and report back if you are still having any issues?
So far so good this evening...
But ive had the odd evening with little or no problems before so I will reserve judgement untill ive had a few days error free.
Have to say, I've been keeping an eye on performance since you said you'd fixed the Bristol problem. I've had zero issues since then over that period which is unheard of to be honest as I normally suffer with timeouts at some point and I do use the internet intensively during the day and evening. I don't want to tempt fate in any way but it's seeming like you may have solved the problem...
I would seem to agree. As this has been going on for me for over a year I am always unsure but the last few days I have had no issues normally seen. Fingers crossed it stays that way for all!
I thought these problems had been resolved but when I logged on about 1 hour ago I was unable to load any internet banking web pages. This was irrespective of the DNS I selected or the browser.
