What is request denied, error 503? Your current IP address has issued more than 60 page requests in a single 2 minute period. Or, Has requested/posted 25k bytes per second for 2 minutes, on average. For the purpose of server stability, we are forced to return a 503 error to further requests until the above counts reduce.. If requests continue at a high rate, then your IP address may be auto-blocked for a period and every page on the site will return 401 errors (permission denied). Why did you get this error? - five common reasons 1. Perhaps you are running some software such as Ad-Aware or AdShield or other newer service that requests more than just the one page at a time. Disable it or reinstall it - it is buggy! 2. Perhaps your web browser tried to 'archive' an entire page including all links .. 3. Perhaps you just clicked very fast, page by page, in which case a short delay will return service to you. What do you do now? well, you can wait a while (a few minutes) and if that does not work, 20+ minutes. Make sure you have disabled any extra software which may be causing multiple page requests.. If you persist in getting this error, then please email webmaster@dslreports.com tell us what unique URL you accessed, and your current IP address, so we can help you.
