Thank you for visiting the SWLing Post. The site is currently in maintenance mode while we investigate and resolve a recent security issue. In the 18 years the SWLing Post has been online, this is the first time we’ve experienced an incident like this. Unfortunately, the malware involved managed to evade both of our paid security protection systems, which is why we have temporarily taken the site offline out of an abundance of caution. To ensure the issue is properly resolved, we have now engaged a professional cybersecurity team to assist with a full investigation, cleanup, and restoration of the site. Because we want to be thorough and ensure the site is completely secure before bringing it back online, this process may take a few days. We sincerely appreciate your patience and understanding while we work to restore the SWLing Post to full operation. Thank you for your continued support. — Thomas Witherspoon SWLing Post
