The site was down twice today. The first time for about 6 hours, the second time for about 30 min. There is a system in place that should notify me when the site is down, but it failed when in happened for the first time. With the help of the hosting company, the source of the problem was fixed. I also decided to upgrade the speed and the amount of storage on the server on which the site is hosted. There are still some configuration steps that I need to complete, but you should already see an increase in response time when browsing the site.
