This is on their website, don't know how long it's been there:
***NOTE: We're still experiencing both internet and telephone issues at our office. Windstream has attempted to troubleshoot the problem(s), but advised it could be due to the extreme heat. Our phones seem to be working (though with intermittent outages), but internet is still an issue. We have a "back up" system which is supposed to cover any potential system outages, but does not seem to be functioning properly. Our sincere apologies for the inconvenience, we thank you for your patience - welcome to Central Arkansas!
