One of our Internet Service Providors made some changes two nights ago which knocked out our email access for more than a day. They claimed the problem was at our end while we claimed the problem was at their end. Our email was back online once they fixed the problem at their end. The downtime was a reminder of the importance of a robust IT infrastructure. We are having a discussion with our ISP as a result as they may not be as robust as we would have liked. Certainly, the service we experienced was not as good as we have been promised.
