# lencr.orgNo, the data on `lencr.org` is never malicious. When a device connects to`lencr.org`, it’s because client software on that device (like a web browser oran app) connected to another site, saw a Let’s Encrypt certificate, and istrying to verify that it’s valid. This is routine for many clients.We can’t speak to whether the *other site* being connected to is malicious. Ifyou’re investigating network activity that seems unusual, then you may want tofocus on the connection that started just before the connection to `lencr.org`.The pattern of clients’ connections to `lencr.org` might look unusual orintermittent. Clients might never retrieve this data; only retrieve subsets ofit; or “cache” some data for efficiency, so they’ll only access it sometimes(the first time they need it, and when the data may have expired).# What exactly is this data for?When client software (like a web browser or an app) connects to a site, and thatsite presents a certificate, the client should verify that the certificate isauthentic and valid. This data helps clients do that in several ways.* Under `c.lencr.org`, we provide Certificate Revocation Lists (CRLs) listingall the unexpired certificates that we issued and later revoked.* Under `i.lencr.org`, we provide copies of our intermediate “issuer”certificates, which are either signed by one of our root certificates or“cross-signed” by another Certificate Authority (CA). A client may use thisdata to confirm the “chain of trust” from the end-entity certificate it’sverifying, via one or more intermediate steps, to a root CA certificate that it# Why “`lencr.org`”?We used to use longer URLs like `http://example.int-x3.letsencrypt.org/`. However,when we issued our new root and intermediate certificates, we wanted tomake them as small as possible. Every HTTPS connection on the web (billions perThe same call, in code.
