What IP Addresses does SiteDash use?

SiteDash connects with your site through HTTP requests. These requests may come from a variety of servers that we refer to as workers. In some cases you may find a firewall, mod_security, or other security implementation on your server to block these requests.

If possible, whitelisting the "SiteDash.app" user agent or the assets/components/sitedashclient/ path would be preferable over whitelisting IPs. We occasionally add or replace servers, so if you have a firewall that requires the whitelisting, please check back here every couple of months or so for updates.

The following IPs are used for general tasks and monitoring:

Internal server name IPv4 IPv6
w2 2a03:b0c0:2:d0::11d:5001
w3 2a03:b0c0:2:f0::31:7001
w4 (lighthouse) 2a03:b0c0:2:d0::13:4001
w5 (monitoring) 2a03:b0c0:2:f0::cc:9001
web1 (rarely) 2a03:b0c0:2:d0::cd:7001

The following IPs are used for extended uptime monitoring:

Cluster Location IPv4 addresses IPv6 addresses
EU-AMS Amsterdam, The Netherlands 2a03:b0c0:2:d0::1123:a001
NA-NYC New York, United States

Each cluster may be assigned additional servers at any time.

If you have a significant number of sites (50-100) that you would like to use Extended Monitoring on, but would like a more local cluster than what we currently offer, please get in touch. We can run our monitoring clusters on a variety of cloud providers with locations all around the world and scale it based on demand.
