+title: Cloudflare traffic not being sent to the geographically closest data center
+---
+
+Due to the way routing on [Cloudflare's Anycast network](https://www.cloudflare.com/learning/cdn/glossary/anycast-network/) works, requests may be sent to data center locations that are not necessarily the closest geographically. For example, if Cloudflare does not have a peering relationship with your network provider or if that cache location is receiving increased traffic or errors, Cloudflare may manually route users on Free, Pro, or Business plans to other data centers. You can check the [Cloudflare System Status](https://www.cloudflarestatus.com/) to see if any maintenance or incidents are occurring.
+
+Most requests are sent to the physically closest cache location, but some requests are sent to other data centers that are able to handle requests without errors. For customers who require their zone to always be served by the closest geographic data center with the highest priority of traffic, contact the Sales team to upgrade to an [Enterprise plan](https://www.cloudflare.com/plans/enterprise/contact/).

+title: Potential ISP blocking of Cloudflare IP addresses
+---
+
+Cloudflare cannot guarantee that your assigned IP addresses are not blocked by any country or Internet service provider (ISP). When Cloudflare proxies your zone, it assigns an IP address to the zone from a shared pool in the Cloudflare network. Cloudflare does not offer dedicated or exclusive IP addresses for users on Free, Pro, or Business plans, nor does Cloudflare rotate assigned IP addresses upon request.
+
+When an ISP blocks your website, you should expect that:
+
+- This is not due to a misconfiguration of your Cloudflare settings.
+- You may see a drop in traffic in your [Cloudflare Analytics](/analytics/).
+- As these actions are taken at the ISP level, Cloudflare does not have the ability to restore Internet connectivity for impacted users.
+
+Enterprise users can lease [static IPs](/byoip/concepts/static-ips/) or get their own IPs advertised using [Bring Your Own IP (BYOIP)](/byoip/). For more information, contact the [Cloudflare Sales team](https://www.cloudflare.com/plans/enterprise/contact/).
+
+It is important to note that an ISP-level block is distinct from other types of website blocking. For example, website owners may enforce certain restrictions (based upon IP, ASN, country, or other factors such as rate limiting) that will return [`1XXX` errors](/support/troubleshooting/http-status-codes/cloudflare-1xxx-errors/) in the HTML body of the response. Website owners configure these blocks, so issues need to be addressed directly with the website owner.
