I haven't been aware of the daily backup slot for the servers, due to usually being fast asleep by that time...
However, there's still the off and on slow response time of the site. Prior to the switch to the new software, the site was almost always quite snappy. Now, I'd say 60% of the time it's still snappy. The rest of the time, though, pages have taken up to a minute to load. If it's not an almost instantaneous page load like it is when it's running smoothly, it averages around 7-10 seconds to load a page for me. Sometimes I get error messages that the browser can't connect to the site. All of this happens during the hours I typically access the site, which is between 7:00am-11:00pm, so none of this should be related to the daily backup.
