Earlier today, network issues caused some problems with the site. During this time, many users complained of slow page load performance. In some cases, users received timeout errors. Our teams have addressed the issues and will continue to work toward better overall site performance.
Update: Unfortunately, we've continued to see some network issues over the past couple of days. Those issues appear to be fixed and we'll continue to monitor the overall performance of the site.
We apologize for the inconvenience and appreciate your patience.
