A computing device may store status information. The status information may be communicated using a first protocol. The status information may indicate data is available. The data may be communicated using a second protocol. ## Claims ### Claim 1 A method comprising: determining, based on a communication failure associated with at least one of a first server or a second server, a polling frequency; polling, by a computing device via a connectionless protocol and at the polling frequency, the first server to determine availability of data associated with the computing device; receiving, via the connectionless protocol and from the first server, an indication that there is data available to the computing device; sending, to the second server and via a reliable protocol, a request for the available data; and receiving, via the reliable protocol, the available data. ### Claim 2 (depends on 1) The method of claim 1, wherein the receiving the available data comprises receiving the available data from the second server. ### Claim 3 (depends on 1) The method of claim 1, wherein the connectionless protocol comprises User Datagram Protocol (UDP). ### Claim 4 (depends on 1) The method of claim 1, wherein the connectionless protocol comprises an unreliable protocol. ### Claim 5 (depends on 1) The method of claim 1, wherein the reliable protocol comprises Transmission Control Protocol (TCP). ### Claim 6 (depends on 1) The method of claim 1, wherein the reliable protocol comprises at least one of an acknowledgement-based protocol or a connection-based protocol. ### Claim 7 A device comprising: one or more processors; and memory storing instructions that, when executed by the one or more processors, cause the device to: determine, based on a communication failure associated with at least one of a first server or a second server, a polling frequency; poll, by the device via a connectionless protocol and at the polling frequency, the first server to determine availability of data associated with the device; receive, via the connectionless protocol and from the first server, an indication that there is data available to the device; send, to the second server and via a reliable protocol, a request for the available data; and receive, via the reliable protocol, the available data. ### Claim 8 (depends on 7) The device of claim 7, wherein the instructions, when executed, further cause the device to receive the available data from the second server. ### Claim 9 (depends on 7) The device of claim 7, wherein the connectionless protocol comprises User Datagram Protocol (UDP). ### Claim 10 (depends on 7) The device of claim 7, wherein the connectionless protocol comprises an unreliable protocol. ### Claim 11 (depends on 7) The device of claim 7, wherein the reliable protocol comprises Transmission Control Protocol (TCP). ### Claim 12 (depends on 7) The device of claim 7, wherein the reliable protocol comprises at least one of an acknowledgement-based protocol or a connection-based protocol. ### Claim 13 A system comprising: a first server device; a second server device; and a computing device configured to: determine, based on a communication failure associated with at least one of a first server or a second server, a polling frequency; poll, via a connectionless protocol and at the polling frequency, the first server to determine availability of data associated with the computing device; receive, via the connectionless protocol and from the first server, an indication that there is data available to the computing device; send, to the second server and via a reliable protocol, a request for the available data; and receive, via the reliable protocol, the available data. ### Claim 14 (depends on 13) The system of claim 13, wherein the computing device is further configured to receive the available data from the second server. ### Claim 15 (depends on 13) The system of claim 13, wherein the connectionless protocol comprises User Datagram Protocol (UDP). ### Claim 16 (depends on 13) The system of claim 13, wherein the connectionless protocol comprises an unreliable protocol. ### Claim 17 (depends on 13) The system of claim 13, wherein the reliable protocol comprises Transmission Control Protocol (TCP). ### Claim 18 (depends on 13) The system of claim 13, wherein the reliable protocol comprises at least one of an acknowledgement-based protocol or a connection-based protocol. ### Claim 19 A non-transitory computer-readable medium storing instructions that, when executed, cause: determining, based on a communication failure associated with at least one of a first server or a second server, a polling frequency; polling, by a computing device via a connectionless protocol and at the polling frequency, the first server to determine availability of data associated with the computing device; receiving, via the connectionless protocol and from the first server, an indication that there is data available to the computing device; sending, to the second server and via a reliable protocol, a request for the available data; and receiving, via the reliable protocol, the available data. ### Claim 20 (depends on 19) The non-transitory computer-readable medium of claim 19, wherein the instructions, when executed, further cause receiving the available data from the second server. ### Claim 21 (depends on 19) The non-transitory computer-readable medium of claim 19, wherein the connectionless protocol comprises User Datagram Protocol (UDP). ### Claim 22 (depends on 19) The non-transitory computer-readable medium of claim 19, wherein the connectionless protocol comprises an unreliable protocol. ### Claim 23 (depends on 19) The non-transitory computer-readable medium of claim 19, wherein the reliable protocol comprises Transmission Control Protocol (TCP). ### Claim 24 (depends on 19) The non-transitory computer-readable medium of claim 19, wherein the reliable protocol comprises at least one of an acknowledgement-based protocol or a connection-based protocol.
