Website down - but only on specific wifi networks

December 19, 2016 160 views

We have this occasional issue that our website goes down - but only on specific Wifi networks. For example, nobody can get to the site from our office, but next door or on mobile internet it's fine. It happens a few times a month, and not just on one network; we've seen it in at least three so far. Any ideas what might be causing it? It's a pretty straightforwards WordPress site, nothing too fancy. And the error message is the usual:

The connection has timed out
The server at is taking too long to respond.
The site could be temporarily unavailable or too busy. Try again in a few moments.

It's happening right now in our office..

Based on what you describe, this is likely to be one of a couple possible issues:

1.) DNS related - if there are DNS records accessible to one network but not another it could cause an issue only in one place. If you previously hosted your site with the ISP that is also providing your Internet access this could happen. It's also possible if you have multiple records that one rather than the other is returned, this would likely cause more sporadic issues but if a bad DNS result is cached locally it could be the source of the problem.

2.) Network routing - The other potential issue is in the routing between your location and your droplet. Our support team can look into this for you so I'd recommend opening a ticket. If you can provide the results of a ping and PTR/traceroute between the network experiencing the problems and your droplet it would help.

Reset WiFi settings:

Turn Off Wi-Fi from the Wireless menu item

From the OS X Finder, hit Command+Shift+G and Copy/Paste the following path:

Select following files:



and move them to Desktop (do not delete for now). This forces OS X to recreate all network configuration files.

Restart WiFi and check.

Solution 2:

If your Ping works (your WiFi connection is fine), then check and modify your DNS server (responsible to connect you to the right website). I would add Google DNS in system preferences- Network -Advanced -DNS and it is the
