Issues with Load Balancers?

[BMGSEO]

Has anyone ran into SEO issues with sites utilizing load balancing systems? We're running into some other technical complications (for using 3rd party tracking services), but I'm concerned now that the setup could have a not-so-good impact from an SEO standpoint.

Unless the load balancing is causing your system to 404 or 500 I cannot see any SEO impact. We did have to change the way we handled session state when we switched to load balancing to ensure state was valid on our shopping cart calls but that is more a developer issue than SEO. Most major hosts now tend to use VM, Cloud or other resource load balancing behind the scenes to keep their costs down without impact to SEO of their clients.
