803 Error
-
I started receiving an 803 error last week for two campaigns and our web dev team has not done any updates to trigger this. Any help on getting this fixed would be greatly appreciated!

Hi there! Tawny from Moz's Customer Support team here.
I think it's pretty unlikely that we'll change the behavior of our crawler, unfortunately.
When we crawl your site we adhere to the “Politeness Policy” so that we don't impact the performance of your site:
-
We do this by dynamically controlling (throttling) the number of URLs that we crawl per minute, per hour. If we determine that your site is responding slowly or there are network issues, we extend the crawl intervals. Following the Politeness Policy protects your site from excessive load.
-
Roger Mozbot schedules and crawls thousands of sites a day.
-
Other items can affect the crawl, including changes to your site, network conditions, how your site crawl is scheduled compared to other crawls, etc.
Hope this helps!

Much depends on where your site lives. I spoke extensively with Bluehost this week because of having same error resurface at odd times and my site correspondingly lowered considerably in MOZ's trust score. (At least at the same time, although I wonder about this.)
You may need to try server load testing for servers using virtual users to learn what limitations currently exist. It helps if you highly optimize your site to load fast (recommend that you use Accelerated Mobile Pages). Monitor CPU loads, ram usage, and database connections/queries to see if they run efficiently. Reasons already exist and more are coming that make these pages load faster to reduce such complications as well as new advertising opportunities to target mobile buyers.
Typically shared servers are managed to some degree by the hosting company. You can call them and perhaps together reset your timing in php configurations. They often won't make the change for you, you have to physically do that, but your web host may walk you through these timing tweaks for your site's TCP connection.
I have another client with the same host but who pays for a VPS ULTIMATE package. That means that his server is unmanaged by the host, but on his site so far, we have not had the TCP connection close to the Moz crawler that we know of.
QUESTION: Moz, any chance you will simply extend the time your crawler takes to reduce these complications?

Hi there! Tawny from Moz's Help Team here.
When you see an 803 error, that means your site closed its TCP connection to our crawler before our crawler could read a complete HTTP response. You don't see this error when you go to the page in your browser because content-length is an outdated component for modern browsers and they will disregard this error, but the intention of our crawler is to report any errors that might be occurring. So the crawler is configured to detect and report such errors.I'm not a web dev (since I'm just here to support our tools) so I can't exactly tell you how to fix this issue. However, one of our very trusted community members, Sha Menz, has a great answer regard 803 errors here: https://moz.com/community/q/how-do-fix-an-803-error
I hope this helps!

After fixing Crawl Errors, how long does it take to for Moz or Google to re-crawl a website?
Last night I found out through Moz that my robots.txt file was blocking any crawling of my website. I fixed the issue. Now do I just sit and wait?

Error help for newbie please
Hi, I signed up after seeing the videos on Udemy and YouTube (white board Friday) So I've started the free trial and am looking forward to getting my site ranking higher. I've crawled my site www.sussexchef.com and its come back with the following errors (please see below. 608 I'm sure this information is very important but I have no idea how to fix the 608, I found a robots.txt in my directory and deleted it as I think that maybe the problem? I crawled the site twice by accident so will have to wait till tomorrow to find out? 404 I found it quite hard to find the broken links at first but once I realized all the information I needed was in the table I think I got them all. did I miss a tutorial or am I just a little out of my depth here? 503 I have no idea how to fix these, I can click the links and it takes my to that page or file. so how can it be the server down? Or is this because they are links to PDF's? should i convert them to jpegs and give them meta data? I'd be grateful for any help anyone has to offer as I'm keen to learn how to promote my site better.

Down for me? Or everyone? 504 errors on campaigns and research tools.
Additionally direct emails to help@moz.com don't work and return a permanent failure error. There's also no verification email coming through when using the message form page to contact support, I'm presuming it's emailing the above email but also failing.
