Err, no. SGIs were first very expensive (3D) graphics workstations and later mostly also-rans in some other markets like storage and general-purpose big servers.
Servers were Sun, x86, HP-PA, IBM R6000 RISC (and probably some more UNIX / RISC systems). Workstations were PC, Sun, Apple (mostly for graphics / design), some NeXT.
Er, yes.
Many media companies onboarded to the web in the early 90's using SGI machines.
The Indy was a very popular multi-host system for such things. It was not a graphics powerhouse and in many low-end configurations its primary function was web serving.
(Disclaimer: I helped build the early web using SGI systems, with many major media companies as clients..)
They even had the "WebFORCE" branding with the "to author and serve" tagline! I also did a lot of early web work on an Indy, and we hosted on a Challenge!
I have a Challenge S right now, and when I got it the drive had web hosting setup for a car dealer.

OK, I see that an Indy went for about the same price as a SPARCstation 5 in 1993. I knew about the low-cost Indy, but not that it was that low cost (for a UNIX workstation, about $5000).
