Internet exchanges in Pennsylvania
Exchanges are attributed to the state through the city they sit in, because PeeringDB records a state for facilities but not for exchanges.

What a Pennsylvania IP address tells you
Pennsylvania's capacity sits in two cities rather than one. Netrality Philadelphia at 401 N Broad lists 51 networks and Equinix PH1 adds 24, while Pittsburgh answers with DataBank PIT1 at 38 networks and Crown Castle Allegheny Center Mall at seven. Both ends interconnect at home, PIT-IX with 35 participants and PhillyIX with 29, and NYIIX Philadelphia adds five more. Sites outside the two cities, such as TierPoint Valley Forge in Norristown and TierPoint Allentown-TekPark in Breinigsville, hold six and five networks.
A Pennsylvania address in a geolocation database comes from the record the operator published for that block, not from any measurement of the device. Mobile networks concentrate subscribers behind regional gateways, so a handset in Norristown or Breinigsville can present an address a lookup places in Philadelphia, or outside Pennsylvania altogether. AT&T, T-Mobile and Verizon each announce mobile traffic from several ASNs, among them AS19540 and AS13644, and a state boundary is not what those announcements follow.
Read the origin ASN and the netname on the specific prefix before trusting a state label. A block announced by a network that appears in the Philadelphia or Pittsburgh facility lists has a clearer tie to Pennsylvania than one filed under the state by a database alone. The snapshot counts 213 network presences across 42 facilities and 69 networks peering locally, which is the footprint any regional claim has to fit inside.

Questions
How many data centres are in Pennsylvania?
The snapshot lists 42 facilities across 13 Pennsylvania cities, holding 213 network presences. Philadelphia and Pittsburgh account for most of them, led by Netrality 401 N Broad at 51 networks and DataBank PIT1 at 38. Norristown, Breinigsville and the smaller cities carry a handful each.
Is there an internet exchange in Pennsylvania?
Three, and two of them carry the traffic. PIT-IX in Pittsburgh has 35 participants and PhillyIX in Philadelphia has 29, with NYIIX Philadelphia at five. Counted together, 69 networks peer inside Pennsylvania instead of carrying that traffic out of the state.
Can I get an IP address in Pennsylvania?
Placement follows the operator's address registration, not a customer's choice of state. A block reads as Pennsylvania when the network holding it registered it there and announces it from a Philadelphia or Pittsburgh presence. That decision belongs to the operator, and mobile ranges often register to a wider area.
