I have been working on some sites in one of the hosting locations I use. I have noticed slow and intermittent performance today. If you have a website created over the past 5 months then it is possible you are affected by slow and intermittent performance from one of the servers from around 11am today.
I have contacted the support desk, (several times) and they are looking into the issue. I will keep an eye on it over the next day or two. I expect this will be resolved within the next 4 hours.
