What San Antonio business internet providers publish, checked November 10, 2026

The AT&T Business Fiber product page lists symmetrical download and upload speeds of up to 300 Mbps, 500 Mbps, 1000 Mbps, 2 Gbps, and 5 Gbps, with the top tier marked "5 GIG Limited availability/areas". Beside its plans, the AT&T Business Fiber product page states "Speeds based on wired connection. Actual speeds may vary. For 5 GIG, single device wired speed maximum 4.7Gbps."

The AT&T Business Fiber product page says "AT&T Business Fiber is a broadband access service in AT&T Fiber-ready buildings."

According to the AT&T Dedicated Internet product page, "A 100% uptime guarantee If your AT&T Dedicated Internet goes out, even for a second, you can request a service level credit." The same passage points to the terms with the words "See AT&T Service Guide for AT&T Dedicated Internet service level agreements (SLAs)."

Separately from that service level wording, the AT&T Dedicated Internet product page on the AT&T Business site has a block about the "AT&T Guarantee® for Business", which lists "Credit for fiber downtime lasting 20 minutes or more, or for wireless or AT&T Internet Air for Business downtime lasting 60 minutes or more if connected to impacted tower at onset of outage." and adds "Wireless downtime must be caused by single incident impacting 8 or more towers. Restrictions and exclusions apply."

Ask AT&T in writing whether the uptime guarantee applies to the plan you are quoted, and use the AT&T provider page for AT&T's residential plans and general details.

Spectrum pages: Enterprise for San Antonio, Business Internet for small business

The Spectrum Enterprise page is the Spectrum page that names San Antonio, while the Spectrum Business Internet small-business page is national and names Texas only in its tax note, so the small-business facts below are not San Antonio specific.

Under its Dedicated Fiber Internet heading, the Spectrum Enterprise page says "Delivered via our private fiber network, Spectrum Internet services are backed by a team that delivers proactive monitoring and responsive service every second of every day.", and its uptime wording reads "100% uptime SLA applies only to Dedicated Fiber Internet, Secure Dedicated Fiber Internet, Ethernet Services, Cloud Connect and Enterprise Trunking."

The Spectrum Business Internet page names the plans Spectrum Business Internet 500, Spectrum Business Internet 750 and Spectrum Business Internet 1 Gig. On the network, the Spectrum Business Internet page says "Data travels over high-speed fiber-optic lines to a nearby fiber node, and a coaxial connection completes the connection to the business premises." On Texas taxes, the Spectrum Business Internet page notes "Internet taxes are extra in Texas." The Wireless Internet Backup note on the Spectrum Business Internet page states "Static IP and Business WiFi not supported when Wireless Internet Backup service is engaged."

The Spectrum Business Internet page lists speed tiers, so confirm the tier for your address with Spectrum. The Spectrum provider page has Spectrum's residential plans.

Google Fiber Business page

The Google Fiber Business page does not name San Antonio, so confirm with Google Fiber that its terms apply at your address.

On static IP, the Google Fiber Business page says "Business 2 Gig also includes a single static IP assignment"

In a question for property managers, the Google Fiber Business page says "To have Google Fiber installed for your business location, we need an access agreement." and continues "This agreement allows us to perform a site survey of your property, and, if the site survey meets our criteria, to install Google Fiber." In its terms footnote, the Google Fiber Business page says "Service eligibility varies based on market." and "If your apartment, condo, or your business is located in a multi tenant property, your eligibility for Google Fiber is subject to the continued agreement between Google Fiber and the property owner."

Ask Google Fiber in writing whether your building needs an access agreement before you order; the Google Fiber provider page has background on the provider.

Astound Business page

The Astound Business Internet page is Astound's company-wide business page, so ask Astound whether its wording applies at your address.

The Astound Business Internet page says "Our High Speed Internet (HSI) product is asymmetrical, meaning the download speed is faster than the upload, but Astound also offers symmetrical services.", and "Our Business Class Internet is symmetrical". On static IP, the Astound Business Internet page says "If you are planning to host an email or FTP server, or a virtual private network, you will need a Static IP." Ask Astound which product the quoted plan is and whether it is the symmetrical one.

What to confirm with a provider before signing

• Ask AT&T Business which support hours apply to the quoted plan, because the AT&T Business San Antonio page says "Supported by dedicated 24/7 customer care".
• Ask Astound which support hours apply to the quoted plan, because its page says "Astound offers 24/7 technical support 365 days a year."

For providers beyond this page, see the business internet providers guide.

How to check a business address

Each provider names its own route. The AT&T Business Fiber product page shows the control "Check availability".

The Spectrum Business Internet page says "Enter your address and ZIP Code" The Astound page says "To get started, enter your address" and then "Our services vary based on location."

Run each provider's own check with the business address. Home internet is a different product from business service, so a household shopper should use the residential San Antonio internet page.
