Natwest is having more trouble with its website this afternoon, and has blamed a cyber attack for the problems. If you're having problems accessing your account, this link may work for you.
Here's the update it released this afternoon:
Due to a surge in internet traffic deliberately directed at the NatWest website, customers experienced difficulties accessing some of our web sites today.
This deliberate surge of traffic is known as a distributed denial of service (DDoS) attack. We have taken action to restore the affected web sites. At no time was there any risk to customers.
We apologise for the inconvenience caused.
Natwest and RBS had problems with their IT systems earlier in the week, too. Thousands of customers were affected by the glitches, which happened to come on Cyber Monday, one of the busiest shopping days of the year.
