Locations and network connectivity
Overview
The following table provides an overview of the various connectivity options supported by Databento and their recommended use cases.
| Connectivity option | Services | Best for | Ports | Latency (90th) |
|---|---|---|---|---|
| Internet | Live, Historical | Lowest cost | 0.5+ ms | |
| Dedicated: Interconnect with AWS, Google Cloud or Microsoft Azure | Live, Historical | Mission-critical, cloud-based applications requiring high uptime or consuming entire feed(s) | 1G | 1.7+ ms |
| Dedicated: Interconnect at proximity hosting location | Live, Historical | Mission-critical, self-hosted applications requiring high uptime or consuming entire feed(s) | 1G | 0.5+ ms |
| Dedicated: Cross-connect with any colocation or managed services provider (MSP) | Live | Applications requiring lowest latency | 10G, 25G | 42.4 μs |
| Dedicated: Colocation with Databento | Live | Applications requiring lowest latency | 10G, 25G | 42.4 μs |
| Peering | Live, Historical | Colocation, hosting and extranet providers, MSPs | 10G, 25G | 0.5+ ms |
Connecting via internet
By default, our client libraries will connect to our gateways over internet, using our public DNS hostnames.
Databento's services are designed to be efficient when consumed over internet. We use a mix of compression and normalization techniques to minimize bandwidth requirements of our data services, so that you can even consume full venue feeds—which would typically require a 10+ gigabit cross-connect—over a regular internet connection.
Hosting your application in close geographical proximity to our gateways is the first step you can take towards ensuring a fast and stable connection. To help you make that determination, here are the locations of our gateways as well as hostnames that you can run a ping or traceroute against:
| Service | Nearest metro | Data center | Address | Public DNS hostname |
|---|---|---|---|---|
| Historical (BO1) | Boston | CoreSite BO1 | 70 Inner Belt Rd, Somerville, MA | hist.databento.com |
| Live (DC3) | Chicago | CyrusOne Aurora I | 2905 Diehl Rd, Aurora, IL 60502 | dc3.databento.com |
| Live (NY4) | New York | Equinix NY4 | 755 Secaucus Rd, Secaucus, NJ 07094 | ny4.databento.com |
There is no strong guarantee that the shortest route between your application and our gateways will be taken even if they're situated in the same data center. To address this issue and achieve stable routes across the internet, Databento relies on blended bandwidth and private peering agreements which are summarized in the table below. If minimizing network variance is important for your use case, we recommend using any of these providers.
| Service | Data center | Transit providers and private peers |
|---|---|---|
| Historical (BO1) | CoreSite BO1 | Lumen, NTT, Telia, Cogent, Verizon, Google, Microsoft, Akamai |
| Live (DC3) | CyrusOne Aurora I | Lumen, Zayo |
| Live (NY4) | Equinix NY4 | Lumen, Hurricane Electric |
If your security policies only allow traffic from designated IPs, ensure that you can route to the entire range of Databento's public IP addresses, from 209.127.152.0 to 209.127.159.255 (or 209.127.152.0/21 in CIDR notation). We are allocated exclusive ownership and usage of these public IPs by ARIN.
You should also allow the following UDP and TCP port ranges used by our services through your access lists and firewalls. The destination ports are port numbers that Databento's servers listen on.
| Protocol | Destination ports |
|---|---|
| NTP | 123 |
| HTTPS (historical) | 443 |
| FTP | 21, 61000-61004 |
| UDP | 13000-13050 |
| TCP (live) | 13000-13050 |

See our dedicated connectivity guide for more details.
Connecting via peering
Databento supports private peering over BGP at CyrusOne Aurora and the Equinix NY2/4/5/6 facilities for our live data, and at Markley One Summer Street for historical data. Our BGP ASN is AS400138 and more info can be found on our PeeringDB profile. We do not support public peering at an IX at this time. Contact support to set up private peering with Databento.
